The first impeachment inquiry against Andrew Johnson was launched by a vote of the United States House of Representatives on January 7, 1867, to investigate the potential impeachment of the  President of the United States, Andrew Johnson.
It was run by the House Committee on the Judiciary.
 The vote authorizing the inquiry was viewed as giving Republicans an opportunity to register their disdain for Johnson without formally impeaching him. Most congressmen had expected that the sentiments in House Committee on the Judiciary would side against impeachment. However, surprising many, the committee voted 5–4 on November 25, 1867, to recommend impeachment (after having held a preliminary vote against it months prior). Despite this recommendation, the House voted 57–108  on December 7, 1867, against impeaching Johnson, with more Republicans voting against impeachment than for it.
 This impeachment inquiry preceded the second impeachment inquiry against Andrew Johnson (launched in January 1868), which played a role in the lead up to the February 24, 1868 impeachment of Johnson.
 Some Radical Republicans had entertained the thought of impeaching President Andrew Johnson since as early as 1866. However, the Republican Party was divided on the prospect of impeachment, with moderates in the party, who held a plurality, widely opposing it at this point. The radicals were more in favor of impeachment, as their plans for strong reform in reconstruction were greatly imperiled by Johnson. Among of the first Radical Republicans to explore impeachment was House Territories Committee chairman James Mitchell Ashley. Ashley was convinced of a baseless conspiracy theory that faulted Johnson for involvement in conspiring in the assassination of Lincoln. Thus, Ashley had strong personal motivation for wanting to remove Johnson from office. Ashley quietly began researching impeachment. Federal impeachment was rare in the United States.
 Several attempts were made by Radical Republicans to initiate impeachment, but these were successfully rebuffed by moderate Republicans in party leadership. After the December 1866 meeting of the House Republican caucus, in an effort to block any further efforts to impeach Johnson, the moderate Republicans leading the party's caucus passed a rule for the Republican caucus which required that both a majority of House Republicans and a majority of members on the House Committee on the Judiciary would be required to approve any measure regarding impeachment in party caucus prior to it being considered in the House. Radical Republicans continued to seek Johnson's impeachment. They disobeyed the rule put in place for the Republican caucus. Radicals proposed a number of impeachment resolutions, which the moderate Republicans often stifled by referring to committees.
 By the start of the year 1867, on a daily basis, Congress was receiving petitions demanding the removal of Johnson. These petitions came primarily from the midwestern states. The petitions were the result of an organized campaign to demand Johnson's removal. The number of signatures on these  petitions varied, as some had as few as three signatures, while other petitions had as many as three hundred signatures.
 By the December 1866 start of the lame-duck third session of the 39th Congress, a number of Radical Republicans were demanding the creation of a select committee to investigate the prospect of impeaching Johnson, but this still faced resistance within the Republican Party caucus. On December 17, 1866, James Mitchell Ashley attempted to open a house impeachment inquiry, but his motion to suspend the rules to consider his resolution saw a vote of 88–49, which was short of the needed two-thirds majority to suspend the rules. Nevertheless, Ashley agreed with Thaddeus Stevens to again bring an impeachment resolution before the full House.
 On January 7, 1867, Benjamin F. Loan, John R. Kelso, and James Mitchell Ashley each introduced three separate impeachment resolutions against Johnson. The House refused to hold debate or vote on either Loan or Kelso's resolutions. However, they did allow a vote on Ashley's impeachment-related resolution. Unlike the other two impeachment bills introduced that day (which would have outright impeached Johnson), Ashley's bill offered a specific outline of how an impeachment process would proceed, and it did not start with an immediate impeachment. Rather than going to a direct vote on impeaching the president, his resolution would instruct the Judiciary Committee to "inquire into the official conduct of Andrew Johnson", investigating what it called Johnson's "corruptly used" powers and "usurpation of power", including Johnson's political appointments, use of his pardon powers (alluding to his pardons for ex-Confederates), vetoes of legislation, selling of confiscated property, and alleged interference with elections. While it gave the general charge of "high crimes and misdemeanors" and named numerous instances of alleged corruption, Ashley's resolution did not specify what the high crimes and misdemeanors Johnson had committed were. The grievances listed in the resolution amounted largely to political grievances which Ashley had against Johnson.
 
The resolution read,  I do impeach Andrew Johnson, Vice President and acting President of the United States, of high crimes and misdemeanors:I charge him with a usurpation of power and violation of law:In that he has corruptly used the appointing power;In that he has corruptly used the pardoning power;In that he has corruptly used the veto power;In that he has corruptly disposed of public property of the United States;In that he has corruptly interfered in elections, and committed acts which, in contemplation of the Constitution, are high crimes and misdemeanors:Therefore,Be it resolved, That the Committee on the Judiciary be, and they are hereby, authorized to inquire into the official conduct of Andrew Johnson, Vice President of the United States, discharging the powers and duties of the office of President of the United States, and to report to this House, whether, in their opinion, the said Andrew Johnson, while in said office, has been guilty of acts which are designed or calculated to overthrow, subvert, or corrupt the Government of the United States, or any department or office thereof; and whether the said Andrew Johnson has been guilty of any act, or has conspired with others to do acts, which, in contemplation of the Constitution, are high crimes and misdemeanors, requiring the interposition of the constitutional power of this House; and that said committee have power to send for persons and papers, and to administer the customary oath to witnesses. The resolution passed in the House 108–39. It was seen as offering Republicans a chance to register their displeasure with Johnson, without actually formally impeaching him. Many Republicans believed that, in the Judiciary Committee, any impeachment resolution would die a quiet death. Of the 108 members of the House that voted in favor of the resolution, 1 was a Democrat, 99 were Republicans, and 7 were Unconditional Unionists, 1 was an independent Republican. Of the 6 to vote against it, 25 were Democrats, 6 were Republicans, 3 were Unconditional Unionists, and 5 were Unionists. 44 members of congress were absent (14 Democrats, 28 Republicans, 2 and Unconditional Unionists). Additionally, Speaker Schuyler Colfax (a Republican) did not vote, as House rules do not require the speaker to vote during ordinary legislative proceedings, unless their vote would be decisive or if the vote is being cast by ballot.
 The official record shows Democrat John Winthrop Chanler as voting in favor of the resolution (thus, this article lists him as having voted as such). However, the New-York Tribune, following the vote, strongly suspected that this was a clerical error.
 The resulting inquiry lasted eleven months, saw 89 witnesses interviewed, and saw 1,200 pages of testimony compiled. Among those that appeared before the House Committee on the Judiciary as part of the inquiry were John Covode (who urged impeachment) Joseph Scott Fullerton, Joseph S. Fowler, Edwin Stanton, Lafayette C. Baker, William Barclay Napton, Rufus Saxton, and Thomas W. Conway, and Jeremiah S. Black. Included among those interviewed were men pardoned by Johnson and men he had fired. John Evans and Jerome B. Chaffee gave testimony related to Johnson's veto of a bill for the admission of Colorado as a state.
 President Johnson was reported to have been angered by the authorization of the inquiry. He kept secret tabs on the inquiry through the Pinkerton Detective Agency. Per the findings of Hinds’ Precedents of the House of Representatives, it does not appear that Johnson sought to be represented by counsel before the committee during the inquiry.
 In the 39th Congress the House Committee on the Judiciary consisted of seven Republicans, one Democrat, and one Unconditional Unionist.
 In the 40th Congress, the House Committee on the Judiciary consisted of seven Republicans and two Democrats. All of the committee members from the previous Congress returned to the committee for the 40th Congress, with the two exceptions of Democrat Sydenham Elnathan Ancona and Republican Daniel Morris, who had both departed the United States House of Representatives. In their place were two new committee members, Democrat Charles A. Eldredge and Samuel S. Marshall and Republican John C. Churchill. Committee member Francis Thomas, who had been elected to the previous congress as a member of the Unconditional Union Party, was now elected to the 40th Congress as a member of the Republican Party.
 In order to comply with Ashley's impeachment resolution, the Judiciary Committee began to slowly conduct an impeachment inquiry, gathering evidence from witnesses in closed sessions.
 On January 14, 1867, the resolution that had been proposed by Benjamin F. Loan on the inquiry was established was finally debated by the full House. Loan gave a long speech to the House in which he used language that was largely interpreted as accusing Johnson of complicity in the assassination of President Lincoln, and which further accused him of participation in a conspiracy to capture the United States Government in the interest of those involved in the southern secession. The resolution was again considered on January 28 and February 4 due to a motion by Thomas Jenckes to refer the resolution to the Committee on the Judiciary. This motion to refer Loan's resolution to the committee already tasked with addressing a prospective impeachment was ultimately agreed to by the House.
 The allegations of misconduct given in the testimony taken by the committee was largely unsupported by evidence. The committee investigated a myriad of allegations against Johnson. Among the matters investigated and for which testimony was taken was the question of whether Johnson played a role in the removal of eighteen missing pages from Lincoln assassin John Wilkes Booth's personal journal. It was speculated whether these pages might have implicated Johnson in the conspiracy behind the assassination. Another allegation investigated was that Johnson had used intimidation or patronage appointments as influence to prevent the admission of the Colorado territory as a state. The committee also investigated whether Johnson had provided pardons to deserters from West Virginia. It also investigated whether or not the commission for the United States' minister to Sweden had been correctly issued. Another matter investigated was the New Orleans massacre of 1866. Also investigated were allegations of fraud in New York City related to import taxes. One allegation investigated (that Johnson had asked the attorney general of the United States whether he believed the Congress was perhaps illegitimate due to the lack of representation for unreconstructed southern states) turned out to be a story fabricated by a journalist.
 The early hearings by the Judiciary Committee were an outlandish affair and were unsuccessful in providing substantive testimony of malfeasance. The Judiciary Committee's first closed-door hearings had been held February 6, 1867, with testimony from Detective Lafayette C. Baker. Baker was famous for having tracked John Wilkes Booth down after Booth assassinated President Lincoln. Baker's testimony set the tone for the series of evidence-devoid allegations that would be delivered in various testimonies, with Baker implication Johnson in several crimes without providing any evidence. He first implicated Johnson in treason, testifying of a wartime letter that he claimed he had once came into possession of on a date he could not recall (but no longer held possession of) which he alleged had been sent from Johnson to Confederate President Jefferson Davis. Baker did not know the contents of the letter. He also declined to disclose who he had received the letter from. However, he testified that he believed that the letter's existence implied that Johnson would "go with" the Confederates. Baker next implicated Johnson with, among other things, involvement with prostitution and bribery. Baker testified about Lucy Cobb, "a disreputable woman, or, in other words, woman of the town" (prostitute), who he had prevented from visiting the White House the previous year. He testified that had disclosed to him that Johnson had secret methods for communicating with "his friends in the South" and that she was herself involved in a trade of selling presidential pardons to confederates.
 The committee investigated whether Johnson had improper connections to southerners that had been sold back railroad assets that had been seized by the Union Army during the Civil War. The possibility that corrupt personal favoritism by Johnson had been involved in these sales was explored. However, Secretary of War Edwin Stanton (well-regarded by Radical Republicans) took responsibility for these sales. Stanton told the committee that he believed the sales were justified because the federal government did not have the know-how needed to successfully run the railroads and the nation's post-war economic recovery required that the railroads be placed into the management of individuals who had the knowledge to successfully operate them.
 The Judiciary Committee ran out of time to complete its inquiry, with the 39th Congress expiring, However, the committee ruled that they had received “sufficient testimony” to continue their investigation in the new 40th Congress. March 2, 1867, two days before the end of the 39th congress, the committee recommended that the matter be further reviewed in the next congress, with committee member James F. Wilson presenting this recommendation to the whole of congress. The full House was then read the committee's majority report which argued that, in the expiring hours of the 39th congress, no affirmative report could be properly considered, and opined that it was "inexpedient to submit any conclusion," with the committee having not fully investigated all charges against the president. This report had been approved by the committee's Republican chairman James F. Wilson, as well as Republican committee members George S. Boutwell, Burton C. Cook, William Lawrence, Daniel Morris, Thomas Williams, and Frederick E. Woodbridge and Unconditional Unionist committee member Francis Thomas. The sole Democratic committee member, Sydenham Elnathan Ancona, submitted a minority report against a continuation of the inquiry. Both reports were ordered printed and laid on the table.
 The 40th Congress consented to the recommendation that the Judiciary Committee made near the end of the 39th Congress, and ordered the committee to continue its inquiry. At the start of the 40th Congress, Congressman Benjamin Buter unsuccessfully urged the Republican caucus to create a special panel to continue the impeachment inquiry. But Congressman James Mitchell Ashley managed to successfully have the inquiry continue in the Judiciary Committee.
 On March 7, 1867, the third day of the 40th Congress, Ashley introduced a resolution calling for the impeachment investigation by the Judiciary Committee to be continue.
 
The resolution read,  Whereas the House of Representatives of the thirty-ninth Congress adopted on 7th of January, 1867, a resolution authorizing an inquiry into certain charges preferred against the President of the United States; and whereas the Judiciary Committee, to whom said resolution and charges were referred, with authority to investigate the same, were unable for want of time to complete said investigation before the expiration of the thirty-ninth Congress; and whereas in the report submitted by said Judiciary Committee on the 2d of March, they declared that the evidence taken is of such a character as to justify and demand a continuation of the investigation by this Congress: Therefore,Be it resolved by the House of Representatives, That the Judiciary Committee, when appointed, be, and they are hereby, instructed to continue the investigation authorized in said resolution of January 7, 1867, and that they have power to sent for persons and papers, and to administer the customary oath to witnesses, and that the committee shall have authority to sit during the sessions of the House, and during any recess which Congress or this House may take.Resolved, that the Speaker of the House be requested to appoint the Committee on the Judiciary forthwith and that the committee so appointed be directed to take charge of the testimony taken by the committee of the last Congress; and that said committee have power to appoint a clerk at a compensation not to exceed six dollars per day, and employ the necessary stenographer.Resolved further, That the Clerk of the House of Representatives be directed to pay out of the contingent fund of the House, on the order of the committee on the Judiciary, such sum or sums of money as may be required to enable the said committee to prosecute the investigation above directed, and such other investigations as it may be ordered to make. John Covode proposed an amendment to the resolution that was understood to have been authored by Benjamin Butler. The amendment would have instead had the continuation of the inquiry be run by a select committee of thirteen members on which the seven members of the Judiciary Committee would all serve. John F. Farnsworth argued against this, arguing that the inquiry should continue to be run through the Judiciary Committee. Citing precedents in the Parliament of the United Kingdom, and declaring that no insult was intended to the Judiciary Committee, Butler argued in favor of a special committee overseeing the inquiry. James G. Blaine argued against moving the inquiry to a special committee, arguing that doing so would be considered a rebuke to the Judiciary Committee. John Martin Broomall voiced similar opposition. John A. Logan voiced support for a special committee, arguing that the Judiciary Committee had no prescriptive right to be handling the matter. John Bingham countered Logan's argument by claiming that, in the eight precedents of federal impeachment cases in the United States, all but one had seen the matter referred to the Judiciary Committee, and that the one exception had led to a ridiculous blunder. After this debate, an overwhelming majority voted to reject the proposed amendment.
 The House adopted Ashley's resolution to renew the investigation without any opposition after both debate and the defeat (by 33–119) of a motion to table it.
 Right after the 40th Congress voted to reauthorize the impeachment inquiry, Speaker Colfax appointed the membership of a number of House committees, including the Committee on the Judiciary. Butler, a strong proponent of impeachment, unsuccessfully requested to be added to the Judiciary Committee, but John Bingham strongly objected to this.
 The 40th Congress' House Committee on the Judiciary resumed the inquiry started by the committee in the previous congress. They held month of closed-door hearings.
 
Johnson and his allies grew more and more frustrated with the impeachment inquiry, which kept expanding in scope. When the committee began investigating Johnson's finances, Johnson irately reacted,  I have had a son killed, a son-in-law die during the last battle at Nashville, another son has thrown himself away, a second son-in law is in no better condition. I think I have sorrow enough without having my bank account examined by a committee of Congress." In March 1867, Radical Republicans, dissatisfied with the slow pace of the inquiry, attempted to bypass that process outlined in Ashley's resolution and instead secure Republican caucus approval for immediate impeachment. John Bingham and James F. Wilson (the chairman of the House Committee on the Judiciary) killed this effort by the Radical Republicans. By mid-1867, impeachment was regularly promoted by chief opponents of Johnson in Congress.
 On June 3, 1867, in a 5–4 vote, the committee voted against sending an impeachment resolution to the full House, with three moderate Republican members joining two Democratic members of the committee in voting against doing so. They, however, also voted in support of censuring Johnson. On July 10, 1867, James F. Wilson reported verbally on behalf of the committee, by its direction, that they anticipated being able to report on or after October 16. He also stated that, as it then stood, five members were of the opinion that high crimes and misdemeanors warranting impeachment had not occurred, while the remaining four members believed that they had. It appeared that Johnson had successfully avoided impeachment.
 The House Committee on the Judiciary had not delivered a report to the full congress, meaning that they had not yet formally closed their inquiry. Johnson would undertake actions that further antagonized Republicans. This would ultimately cause increased Republican anxiety over Johnson's obstruction and lead to the Judiciary Committee reversing their majority stance on impeachment. The first of these actions came when Henry Stanbery (the attorney general of the United States) issued at the request of Johnson a legal opinion which, combined with an earlier opinion issued at the request of Johnson in March, put forth an interoperation of the law that decreased the power of military district commanders in the South. The Reconstruction Acts that had been passed over the vetoes of Johnson had created five military districts in the South and had given broad powers to the commanders of those districts to enforce the Reconstruction Acts. However, the attorney general's legal opinions found that the commanders had no power to remove local officials who acted against congressional policies. The legal opinion also undermined restrictions on former confederates voting.
 The committee would resume collecting evidence for the impeachment inquiry. On July 17, 1867, the House agreed to an amended version of a resolution by John Covode that instructed the House Committee on the Judiciary to, in their investigation, inquire into new a charge levied against the president. The new charge was that Johnson had, allegedly at the request of Lincoln assassination conspirator John Surratt's counsel, given a full pardon to Confederate Stephen F. Cameron. The resolution instructed the committee to look into this action, which it declared would demonstrate Johnson's "sympathy with the men who murdered the President" if true. The resolution also instructed the committee to, in the first week of the second session of the 40th Congress, report evidence to the House on this together with the testimony already collected in the impeachment inquiry. The second session of the 40th Congress would begin on December 2, 1867.
 Over the 1867 summer congressional recess (which lasted from July 21 through November 20, 1867), sentiments among Republicans shifted further with more Republicans coming to side in favor of impeachment due to continued acts by Johnson that antagonized Republicans. One such act was Johnson's suspension of Secretary of War Edwin Stanton and replacement of him with Ulysses S. Grant as secretary of war ad interim on August 12, 1867, taking advantage of a loophole in the Tenure of Office Act created by the Senate being in recess. Another act was Johnson's subsequent firing of Generals Philip Sheridan (who had been in charge of Texas and Louisiana), which was soon followed by his August 12, 1867 firing of Daniel Sickles (who had been in charge of North Carolina and South Carolina), which further contributed to Republican furor. Johnson had fired them against Grant's advice. Both Sheridan and Sickles had acted in their offices to protect policies extending civil rights to African Americans.
 During an 1867 summer meeting, held in response to provocative actions taken by Johnson, more conservative Republicans were able to kill an effort by Radical Republicans to call for an October session of congress dealing with impeachment. This effort, led by Radical Republican Representatives George S. Boutwell, Benjamin Butler, and Thaddeus Stevens and Senators Charles D. Drake and Charles Sumner would have ended the 1867 summer congressional recess. The promoters of this hoped that they could act against intrigue by Johnson and continue to push for his impeachment in the special session. However, Conservative Republicans, led by Representatives John Bingham and James G. Blaine and Senators Lyman Trumbull and William P. Fessenden succeeded in blocking this effort.
 In October 1867, rumors had been published in newspapers that the committee's stance on impeachment had changed. The rumors were characterized as baseless by two of the three moderate Republicans that had previously voted against impeachment. Rumors particularly focused on Churchill and Wilson as individuals that had changed their positions. These were fueled by pro-impeachment committee member William Lawrence claiming to the press that it was true that two non-specified members had switched their positions to now favor impeachment. However, on October 25, John C. Churchill released a statement in which he denied have shared with anyone anything that indicated that he had changed his mind. On October 31, James F. Wilson denied rumors that he had written a correspondence declaring favor for sending an impeachment resolution to the full House. However, Wilson did not indicate his position. Because the Judiciary Committee left its proceedings confidential, when Congress reconvened after the recess, most congressmen were still under the belief that the pending majority report would be against impeachment, just as the committee had previously sided in their earlier July vote.
 Despite having stated in October that he had given nobody any indication of a change of mind, in actuality, John C. Churchill had indeed changed his mind in favor of impeachment by the time Congress' recess ended in November. Consequentially, on November 25, 1867, the House Committee on the Judiciary voted in a 5–4 vote to recommend impeachment proceedings, and to submit its report to the House. The majority approved a resolution which read, "Resolved, That Andrew Johnson, President of the United States, be impeached of high crimes and misdemeanors." The minority on the committee that opposed impeachment had instead proposed ending the inquiry without an impeachment resolution by sending instead the House a resolution that would have read, "Resolved, That the Committee on the Judiciary be discharged from the further consideration of the proposed impeachment of the President of the United States, and that the subject be laid upon the table."
 
After the committee vote became public, Churchill published a lengthy letter in The New York Times explaining the reason for his change of mind, writing in part,  The President in the exercise of his constitutional powers, by such changes of military commanders, or such withdrawal of troops from the reconstructed States, or such other acts as should destroy the confidence of loyalists and freedmen in prompt military protection in the exercise of their suffrage, at any time before the new State Governments shall have been established, and shall have set in operation a machinery of their own for the protection of their citizens, would make it impossible to carry a single Southern State in accordance with the views of a majority of Congress. The committee submitted three reports to the full House, a majority report and two dissenting minority reports.
 The majority report in favor of impeachment was written by Radical Republican committee member Thomas Williams and listed seventeen instances in which he argued Johnson had reached the threshold of impeachment. The report wrote that the primary issue to fault Johnson with was, "the great salient point of accusation, standing out in the foreground, and challenging the attention of the country, is the usurpation of power, which involves, of course, a violation of law." He argued that Johnson had undermined Congress.
 The majority report was poorly written, with an unfocused and rambling style that undermined what valid points it made. Harper's Weekly opined that it did not, "inspire general confidence". The Chicago Tribune, which was sympathetic to the Radical Republican cause, even opined that the charges made in it were, "inferential and circumstantial". The New York Times believed that the report actually helped the president by debunking persistent rumors that he had been involved in the conspiracy to assassinate Lincoln.
 
The report characterized Johnson as having undermined the United States Congress with the intent of empowering the former Southern rebels. In the Report, Williams wrote that Johnson had been acting in the interest of,  The one great the purpose of reconstructing the shattered governments of the Rebel states in accordance with his own will, in the interests of the great criminals who carried them into the rebellion, and in such a way as to deprive the people of the loyal States of all chances of indemnity for the past or security for the future. 
The report alleged that Johnson had acted in the interest of empowering the former Southern rebels,  By pardoning their offenses, resorting lands, and bringing them back, their hearts unrepentant, and their hands yet red with the blood of our people, into a condition where they could once more embarrass and defy, if not absolutely rule the government in which they had vainly endeavored to destroy. The report characterized the alleged intent of Johnson to empower the former Southern rebels in such a manner as being, "the great master-key which unlocks and interprets all of....[Johnson's] special acts of mal-administration."
 The report levied the following seventeen charges against Johnson:
 One minority report was agreed to by the two Democratic members (Marshall and Eldredge), while the other was agreed to by the two moderate Republicans that had voted against recommending impeachment (Woodbridge and Wilson).
 The Democratic minority report, was written by Marshall, and dissented from all criticism of Johnson. The Republican minority report, written by Wilson, wrote that, while they were against impeachment, they believed Johnson, "deserves the censure and condemnation of every well-disposed citizen." It argued that the Congress should wait and let Americans remove Johnson from office in the 1868 presidential election. It declared that Johnson, "has disappointed the hopes and expectations of those who placed him in power. He had betrayed their confidence and joined hands with their enemies." However it also declared, "judge him politically, we must condemn him. But the day of political impeachments would be a sad one for this country.". In the report, Wilson also wrote that, "political unfitness and incapacity must be tried at the ballot box, not in the high court of impeachment."
 The Republican minority report argued that impeachment required a criminal offense and that, in impeachment trials, the Senate acted as a court, "of special criminal jurisdiction," and therefore needed to follow legal forms. He argued that impeachment trials were not to be political procedures. Without evidence, he argued that judicial rules of evidence were required to be applied in Senate impeachment trials and that, in such trials, the Senate could only be able to try offenses, "known to the Constitution, or to the laws of the United States." Wilson made weak arguments in support of this, often using incomplete logic. Wilson's Republican majority report also gave effective rebuttals of the factual charges issued in the majority report.
 While the majority report had found American precedents to support its position that impeachment did not require a legal crime to be committed, Wilson argued the practical considerations of this theory in the Republican minority report. He voiced concern that, if impeachment were entirely a political process, it might mean that a president could be impeached merely for policies that are unpopular with their opponents.
 Later on November 25, 1867, on behalf of the committee, Boutwell submitted to the House the majority report and the impeachment resolution. It was only then that those not on the committee learned that the committee had decided to support impeachment. The impeachment resolution reported by the committee simply read, "Resolved, That Andrew Johnson, President of the United States, be impeached of high crimes and misdemeanors."
 Boutwell then submitted to the House the testimony taken by the committee in its inquiry. After this, the minority reports were submitted by James F. Wilson and Samuel S. Marshall The House then approved a motion by Boutwell to have the reports printed together and to postpone further consideration of the subject of impeachment until December 4, 1867. It was only after the reports were published that those not on the committee on found out that the change of vote in the House Committee on the Judiciary was due to Churchill having changed his stance on impeachment.
 On December 5, 1867, the House brought the Committee on the Judiciary's impeachment recommendation to the floor for consideration, and discussion was thereafter held on the impeachment resolution reported by the Judiciary Committee, with George S. Boutwell presenting a case for impeachment and James F. Wilson presenting a case against it.
 While conservative Republicans were confident that they would defeat impeachment, Radical Republicans were confident that they could succeed in securing impeachment. However, in the Judiciary Committee's vote, two of the committee's seven Republican members (each being two of the committee's three moderate Republicans) had opposed impeachment. This underscored the reality that Republicans remained divided on whether Johnson had committed conduct worthy of impeachment, with many moderate Republicans still having little appetite for an impeachment.
 At the time, there was a disagreement between Radical Republicans and conservative Republicans as to what constituted a "high crime and misdemeanor", which, along with treason and bribery constituted the sole grounds for which impeachment was allowed under the United States Constitution. Conservatives supported the theory put forth by the defense in a number of earlier federal impeachments that government officials only could be impeached for what constituted an indictable violation of criminal statutes or common law. Their support for this theory at that time largely arose from fears for the institutional and political effects impeachment would have on the nation's stability. Radical Republicans, on the other hand, believed in a more broad view on what "high crimes and misdemeanors" encompassed, believing that the nation's framers had intended for "malfeasance, nonfeasance, and, in some cases, misfeasance," to be the subject of impeachment. They cited English precedents, earlier American impeachments, and a great consensus among most early nineteenth-century American constitutional commentators to support this view. They also cited the views of the likes of early American legal scholars such as William Duer, James Kent, William Rawle, and Joseph Story, as well as the authors of The Federalist Papers.
 The House Committee on the Judiciary's Radical Republicans selected, from their ranks, to have George S. Boutwell argue the case for impeachment to the house. He made a four-hour presentation, stretched over two legislative days (December 5 and 6, 1867), which historian Michael Les Benedict later described as, "the clearest, most eloquent, and most convincing argument for the liberal view of the impeachment power". His speech largely focused on the question of whether the president's activities were legally impeachable. The speech lasted two hours.
 Boutwell argued that there needed to be a broad interpretation of impeachment powers. He assailed the notion that impeachment required a clear violation of the law in order to be applied. Instead, citing British precedent and debates from the Constitutional Convention, he argued that impeachment was intended to be used in instances where public trust had been violated, and that impeachment was to be used when an officer refused to "faithfully execute" their office. He argued that America could not wait until the next presidential election to remove an unsuitable president. Boutwell argued that impeachment power, "is subject to no revision or control", but is rather solely to be guided by the judgement of the House of Representatives.
 Boutwell also argued that Johnson had committed flagrant misdeeds that approached criminality in his subversion of the law and refusal to uphold the law, and therefore, his actions had been clearly impeachable. He cited Johnson's veto of the Reconstruction Acts which the congress had overwhelmingly passed. He cited Johnson's urging for southern states under federal control to refuse to ratify the Fourteenth Amendment to the United States Constitution. He also cited Johnson's creation of provisional governorships without authorization, and appointment of provisional governors that Boutwell claimed were ineligible to take official loyalty oaths due to their participation in the Confederacy. Citing these and other actions, Boutwell alleged that Johnsons actions were intended to return Confederates to power in the state and national governments against the judgement of Congress. Boutwell argued, "can there be any doubt as to his purpose, or doubt as to the criminality of his purpose and his respojnsibility under the Constitution?"
 Boutwell also framed a portion of his argument around the notion that impeachment could stop Johnson from interfering in the southern states during the 1868 presidential election, citing specific concerns that Johnson could suppress the vote of African Americans.
 
Boutwell argued,  "To this House is given under the Constitution the sole power of impeachment; and this power of impeachment furnishes the only means by which we can secure the execution of the laws, and those of our fellow-citizens who desire the administration of the law ought to sustain this House while it executes the great law which is in its hands and which is nowhere else, while it is performing a high and solemn duty resting upon it by which that man who has been the chief violator of the law shall be removed, and without which there can be no execution of the law anywhere.....If we neglect or refuse to use our powers when the case arises demanding decisive action, the Government ceases to be a Government of laws and becomes a Government of men." After Boutwell's presentation, James F. Wilson, chairman of the House Committee on the Judiciary took to the floor to argue against impeachment. Wilson argued that while Johnson was the "worst of presidents", his opposition to the positions of the Republican Party was not illegal. Wilson argued that, despite Boutwell's assertion that it did, the House did not have lone authority to determine what constitutes an "impeachable offense". Wilson warned that a broad interpretation of impeachment powers, as Boutwell championed, in theory could allow the House to effectively dictate the policy of presidents. He spent half of his speech arguing that impeachment was only reserved for indictable crimes, and the other half attacking those who opposed this position.
 Wilson characterized the part of Boutwell's argument that had argued impeachment could stop Johnson from interfering in the southern states during the 1868 presidential election as Boutwell effectively arguing the House should be allowed to impeach Johnson for something he could do, rather than some thing he had done. Wilson argued, "this would lead us even beyond the conscience of this house."
 Wilson also argued that much of Boutwell's argument was inconsistent with the majority committee report. Indeed, Boutwell's speech had a number of inconsistencies with the case made in the majority report. Boutwell's speech, at one point, had dismissed English precedents as irrelevant to impeachment under the United States constitution, despite the fact that the majority report cited English precedents. Boutwell had also argued against the minority's stance by characterizing their view as one under which an officer who committed murder in such a manner that they would be outside of United States court jurisdiction would be immune to impeachment. However, the majority report had explicitly stated a belief that murder would not be an impeachable offense, as it would not directly relate to officeholding. Michael Les Benedict has opined, "Wilson's blunt analysis of the inconstancies between Boutwell's brilliant speech and William's mediocre report did tremendous damage to the impeachers' case."
 In his closing remarks, Wilson asked, "if we cannot arraign the president for a specific crime, for what are we to proceed against him?...If we cannot state upon paper a specific crime, how are we to carry this case to the Senate for a trial?"
 After finishing his speech on December 6, 1867, Wilson motioned to lay the resolution on the table. This motion angered the many Radical Republicans that had prepared speeches of their own on the question of impeachment and felt that a successful motion to table would allow Republicans to evade the question of impeachment, going without a direct vote on the matter. Several Radical Republicans filibustered the motion. On December 7, 1867, Radical Republicans reached a quid pro quo agreement with Wilson in which they would end their filibuster and he would withdraw his motion to table the resolution in return for the House proceeding immediately to a vote on the resolution, rather than allowing further debate. As a result of this, general debate was not permitted on the resolution before it was voted on, with debate instead being limited to the speeches that had been delivered by Boutwell and Wilson.
 On December 7, the House voted against impeachment by a margin of 57–108, with 66 Republicans, 39 Democrats, and one member congressmen of other party affiliations voting against impeachment; and with all votes for impeachment coming from Republicans. 22 members of congress were absent (17 Republicans, 4 Democrats, and 1 independent Republican). Speaker Schuyler Colfax (a Republican) did not vote, as House rules do not require the speaker to vote during ordinary legislative proceedings, unless their vote would be decisive or if the vote is being cast by ballot.
 One motivating factor for Republicans' decision to vote against impeachment may have been the successes Democrats had in the 1867 elections, including winning control of the Ohio General Assembly, as well as other 1867 election outcomes, such as voters in Connecticut, Minnesota, New York, and Ohio turning down propositions to grant African Americans suffrage by large margins. Other concerning election results included the very narrow margin-of-victory with which the Republican nominee won the 1867 Ohio gubernatorial election. Only in the states of Michigan and Kentucky did Republicans improve upon their 1866 election performances in 1867, while the remaining eighteen states with elections saw Republicans lose sizable ground over the previous elections. Michael Les Benedict has suggested that, as a result of these election results, in the Republican caucus, "the centrists, who might have favored impeachment had the elections demonstrated radical strength," were left, "divided, most of them opposing impeachment."
 Michael Les Benedict's analysis shows correlation between congressmen's votes in this impeachment vote and voting records in the 40th Congress votes on the matter of currency expansion, as well as voting records on Reconstruction issues during the 39th Congress.
 Radical furor over the conservative and moderate Republicans' votes against impeachment threatened a schism in the Republican Party. Two days after the failed impeachment vote, Radicals met at Thaddeus Stevens' residence to discuss creating a separate congressional organization for Radicals, separate from the Republican Party.
 On December 13, 1867, members of the House availed themselves of freedom of debate in the Committee of the Whole on the state of the Union, and several members discussed the failed impeachment resolution at length.
 With Johnson feeling liberated from the threat of impeachment, he began acting even more aggressively. He made moves that, combined with earlier actions, made it so every reconstructed state was being overseen by officers more sympathetic to former rebels than Southern loyalists to the union. On December 28, 1867, he removed John Pope from his position of command over Georgia and Alabama and Edward Ord from his position of command over Arkansas and Mississippi, replacing them respectively with the more conservative George Meade and the immensely conservative Alvan Cullem Gillem. He also substituted Meade's subordinate, Wager Swayne (who Meade had been delegating authority over Alabama to).
 On January 22, 1868, the House approved by a vote of 99–31 a resolution to launch a second impeachment inquiry against Andrew Johnson, this time run by the House Select Committee on Reconstruction. At a February 13, 1868 committee meeting, a vote on a motion to table consideration of a resolution proposed by Stevens to impeach Johnson had effectively signaled that five of the committee's members still stood opposed to impeachment, unchanged in their position since the December 1867 vote. After the February 13 vote, it momentarily appeared that the prospect of impeachment was dead.
 While impeachment appeared to be a dead issue after the February 13, 1868 vote by the Committee on Reconstruction, the prospect of impeachment would receive new life days later. On February 21, 1868, Johnson, in violation of the Tenure of Office Act that had been passed by Congress in March 1867 over Johnson's veto, attempted to remove Edwin Stanton, the secretary of war who the act was largely designed to protect, from office. On February 10, the House voted to move any further responsibility over impeachment away from the Committee on the Judiciary and to the Select Committee on Reconstruction. On February 21, 1868, Thaddeus Stevens submitted a resolution to the House resolving for the evidence taken on impeachment by first impeachment inquiry into Johnson be referred to the Select Committee on Reconstruction (who were conducting the second impeachment inquiry), and that the Committee on Reconstruction "have leave to report at any time". This resolution was approved by the House. On February 22, the Select Committee on Reconstruction submitted to the House an impeachment resolution and a report that recommended Johnson be impeached for high crimes and misdemeanors. On February 24, 1868, the United States House of Representatives voted 126–47 to impeach Johnson for "high crimes and misdemeanors", which were detailed in eleven articles of impeachment passed in separate votes held roughly a week after the impeachment resolution was adopted.
 The primary charge presented against Johnson in the articles of impeachment that were adopted was that he had violated the Tenure of Office Act by removing Stanton from office. It was decided by the committee tasked with drafting the articles of impeachment that they would not include any of the charges that had been recommended by Thomas Williams' Judiciary Committee majority report in the first impeachment inquiry against Johnson. The New York Times reported that inclusion of those claims would be seen as fatally harming the, "moral and legal effect of the prosecution" in Johnson's impeachment. The articles of impeachment that were ultimately produced by the committee were narrow in their focus and were legalistic and molded on criminal indictment, likely in direct reaction to the failure of the broad allegations cited in the 1867 effort to persuade the House members.
 Johnson was narrowly acquitted in his Senate trial, with the Senate voting 35 to 19 votes in favor of conviction, one vote short of the two-thirds majority needed to convict.
