Candidate passages:
Grimes was elected as a Republican to the U.S. Senate in 1859 and reelected in 1865.
He served in the Senate from March 4, 1859, until December 6, 1869, when he resigned due to ill health.
In the Senate, he served as chairman of the Committee on the District of Columbia (in the 37th and 38th Congresses), and the Committee on Naval Affairs (in the 39th through 41st Congresses).
He also served on the Joint Committee on Reconstruction which drafted the Fourteenth Amendment to the United States Constitution.
In 1861 Grimes was a member of the peace convention held in Washington, D.C., in an effort to devise means to prevent the impending Civil War.
In December of 1861, he introduced the senate bill which led to the creation of the Medal of Honor (initially only for Navy and Marine personnel).
During President Andrew Johnson's impeachment trial, Grimes broke party ranks, along with six other Republican senators and voted for acquittal.
These seven Republican senators were disturbed by how the proceedings had been manipulated in order to give a one-sided presentation of the evidence.
Senators William Pitt Fessenden, Joseph S. Fowler, James W. Grimes, John B. Henderson, Lyman Trumbull, Peter G. Van Winkle, and Edmund G. Ross of Kansas, who provided the decisive vote, defied their party and public opinion and voted against impeachment.
After the trial, Ben Butler conducted hearings on the widespread reports that Republican senators had been bribed to vote for Johnson's acquittal.
In Butler's hearings, and in subsequent inquiries, there was increasing evidence that some acquittal votes were acquired by promises of patronage jobs and cash cards.
Grimes died in Burlington on February 7, 1872, aged 55.
He is buried in the Aspen Grove cemetery, in Burlington.
The plot of land that his home was once located on is now home to an elementary school that bears his name.
The town of Grimes, IA is named for James W. Grimes. 
Thirty-six "guilty" votes were required to remove Johnson from office.
On all three occasions, 35 Senators voted "guilty" and 19 "non-guilty".
As the Constitution requires a two-thirds majority for conviction in impeachment trials, Johnson was acquitted.

In June 2013, the Senators traded impending free agent Sergei Gonchar to the Dallas Stars for a sixth-round pick in the 2013 NHL Entry Draft.
The Senators chose Chris Leblanc with the pick.
On July 5, two moves came about that changed the face of the franchise.
In a surprise move that shocked Ottawa fans, captain and multiple franchise record holder Daniel Alfredsson signed a contract to play with the Detroit Red Wings, ending his 17-year association with Ottawa.
"It pretty much came down to a selfish decision in terms of I have not won a Stanley Cup, a big priority for me," Alfredsson explained in a candid conference call with the media.
He continued explaining how hard of a decision it was and gave his reasoning.
"I feel that in Ottawa they are getting closer and closer and they have a really bright future in front of them, but at this point in my career there's not much left," Alfredsson said.
"I don't have the time to wait for that."
In a later press conference, Alfredsson expressed his dissatisfaction in negotiations with the Senators.
Alfredsson stated that an understanding to compensate Alfredsson for the low salary he had taken in the 2012–13 season was not lived up to.
Alfredsson had taken a below-value $1-million salary in 2012–13 in his contract to lower the long-term salary cap hit for his contract, but was not expecting to play the season.
When Alfredsson decided to play the 2012–13 season, he had expected to re-negotiate the contract at that time, but the Senators did not re-open contract negotiations, and Alfredsson decided to play the season at the salary and seek compensation in the 2013–14 contract.
The Senators wanted to pay Alfredsson his market value for 2013–14, without any extra to cover 2012–13.
Later on July 5, the Senators made a major trade with the Anaheim Ducks, picking up multiple 30-goal scorer Bobby Ryan.
The Senators had to give up first-year player Jakob Silfverberg, junior prospect Stefan Noesen and the team's first-round pick in the 2014 NHL Entry Draft.
Ryan, who had been the subject of many trade rumours, tweeted "I'm coming in hot, Ottawa", a reference to the Top Gun movie.
Ryan is expected to play on the top line with Jason Spezza and Milan Michalek.
The Senators signed two free agents, forward Clarke MacArthur from Toronto, and defenceman Joe Corvo from Carolina.
Corvo had previously played with Ottawa from 2006–2008 and was a member of the team that made it to the 2007 Stanley Cup Final.
Forward Peter Regin and defenceman Andre Benoit left the team as free agents, Regin to the New York Islanders and Benoit to Colorado. 
Peter Godwin Van Winkle (September 7, 1808April 15, 1872) was a United States Senator from West Virginia.
Born in New York City, he completed preparatory studies, studied law, and was admitted to the bar, commencing practice in Parkersburg, Virginia (now West Virginia) in 1835.
He was president of the town board of trustees from 1844 to 1850 and was a member of the Virginia State constitutional convention in 1850.
He was treasurer and later president of the Northwestern Virginia Railroad Co. in 1852 and a member of the Wheeling reorganization convention in 1861.
He was a delegate to the State convention which framed the constitution of West Virginia and a member of the West Virginia House of Delegates in 1863.
Upon the admission of West Virginia as a State into the Union, he was elected as a Unionist to the U.S. Senate and served from August 4, 1863, to March 4, 1869.
While in the Senate, he was chairman of the Committee on Pensions (Fortieth Congress).
During President Andrew Johnson's impeachment trial, Van Winkle broke party ranks, along with six other Republican senators and voted for acquittal.
These seven Republican senators were disturbed by how the proceedings had been manipulated in order to give a one-sided presentation of the evidence.

Van Winkle was a delegate to the Southern Loyalist Convention at Philadelphia, Pennsylvania in 1866; he resided in Parkersburg, where he died in 1872.
Interment was in Riverview Cemetery.
Marshall Van Winkle, Peter Van Winkle's grandnephew, was a U.S. Representative from New Jersey in the Fifty-ninth Congress.
His former home at Parkersburg is located in the Julia-Ann Square Historic District., it's known as the Peter G. Van Winkle House. 
Joseph Smith Fowler (August 31, 1820April 1, 1902) was a United States Senator from Tennessee from 1866 to 1871.
Fowler was born in Steubenville, Ohio.
He graduated from Grove Academy in that city and subsequently from Franklin College in New Athens, Ohio in 1843.
He taught school in Shelby County, Kentucky in 1844.
He served as a professor of mathematics at Franklin College in Davidson County, Tennessee from 1845 to 1849.
He studied law in Bowling Green, Kentucky and was subsequently admitted to the bar and practiced in Tennessee until 1861.
He also served as president of Howard Female College in Gallatin, Tennessee from 1856 to 1861.
Fowler was an ardent Unionist.
He served as State Comptroller of Tennessee from 1862 until 1865.
The official "Tennessee Blue Book" states that the holder of that office during this period was "Joseph S. Foster".
It is likely that the "Biographical Directory" is the correct source; the Confederate state government of Tennessee was never very effective and largely dysfunctional due to the early loss of much Tennessee territory to Union forces by the Confederates and also because neither the Confederacy nor slavery had ever had much public support in East Tennessee.
Most of the state was under the control of the Union military government of Abraham Lincoln's appointed governor, Andrew Johnson, for most of the duration of the American Civil War; his government was fairly functional and it is likely that Fowler served this regime as Comptroller and that the "Blue Book" records his name erroneously.
In 1866 Tennessee became the first former Confederate state to be readmitted to the Union; the Tennessee General Assembly elected Fowler to the Senate, where his service began on July 24, 1866.
Fowler became a part of the majority Republican caucus.
In the 40th Congress he served as chairman of the Committee on Engrossed Bills.
During President Andrew Johnson's impeachment trial, Fowler broke party ranks, along with six other Republican senators, and in a courageous act of political suicide, voted for acquittal.
These seven Republican senators were disturbed by how the proceedings had been manipulated in order to give a one-sided presentation of the evidence.
Senators William Pitt Fessenden, Joseph S. Fowler, James W. Grimes, John B. Henderson, Lyman Trumbull, Peter G. Van Winkle, and Edmund G. Ross of Kansas, who provided the decisive vote, defied their party and public opinion and voted against impeachment.

In Butler's hearings, and in subsequent inquiries, there was increasing evidence that some acquittal votes were acquired by promises of patronage jobs and cash cards.
He did not seek a subsequent term in the Senate upon the expiry of his term in 1871.
He also did not return to Tennessee to live, but remained in Washington DC, practicing law there until shortly before his death in 1902.
His remains were interred at Lexington Cemetery in Kentucky.
