This report provides an overview of the development of the process for appointing the Director of the Federal Bureau of Investigation (FBI), briefly discusses the history of nominations to this position, and identifies related congressional hearing records and reports. Two appendixes provide background and legal analysis regarding a 2011 statute that allowed Robert S. Mueller III to be appointed to a second, two-year term. Federal statute provides that the Director of the FBI is to be appointed by the President by and with the advice and consent of the Senate. When there is a vacancy or an anticipated vacancy, the President begins the appointment process by selecting and vetting his preferred candidate for the position. The vetting process for presidential appointments includes an FBI background check and financial disclosure. The President then submits the nomination to the Senate, where it is referred to the Committee on the Judiciary. The Committee on the Judiciary usually holds hearings on a nomination for the FBI Director. The committee may then vote to report the nomination back to the Senate favorably, unfavorably, or without recommendation. Once reported, the nomination is available for Senate consideration. If the Senate confirms the nomination, the individual is formally appointed to the position by the President. Prior to the implementation of the current nomination and confirmation process, J. Edgar Hoover was Director of the FBI for nearly 48 years. He held the position from May 10, 1924, until his death on May 2, 1972. The current process dates from 1968, when the FBI Director was first established as a presidentially appointed position requiring Senate confirmation in an amendment to the Omnibus Crime Control and Safe Streets Act of 1968. The proposal for a presidentially appointed Director had been introduced and passed in the Senate twice previously, but had never made it through the House. Floor debate in the Senate focused on the inevitable end of Hoover's tenure (due to his advanced age), the vast expansion of the FBI's size and role under his direction, and the need for Congress to strengthen its oversight role in the wake of his departure. In 1976, the 10-year limit for any one incumbent was added as part of the Crime Control Act of 1976. This provision also prohibits the reappointment of an incumbent. As with the previous measure, the Senate had introduced and passed this provision twice previously, but it had failed to pass the House. Since 1972, seven nominations for FBI Director have been confirmed, and two other nominations have been withdrawn. Due to a 2011 statute allowing for the reappointment of a specific incumbent, two of the seven confirmed nominations were of the same person, Robert S. Mueller III. Each of these nominations is shown in Table 1 and discussed below. L. Patrick Gray III. On the day after the death of long-time Director J. Edgar Hoover, L. Patrick Gray was appointed acting Director. President Richard M. Nixon nominated Gray to be Director on February 21, 1973. Over the course of nine days, the Senate Committee on the Judiciary held hearings on the nomination. Although Gray's nomination was supported by some in the Senate, his nomination ran into trouble during the hearings as others Senators expressed concern about partisanship, lack of independence from the White House, and poor handling of the Watergate investigation. The President withdrew the nomination on April 17, and Gray resigned as acting Director on April 27, 1973. Clarence M. Kelley. Clarence M. Kelley was the first individual to become FBI Director through the nomination and confirmation process. A native of Missouri, Kelley was a 21-year veteran of the FBI, becoming chief of the Memphis field office. He was serving as Kansas City police chief when President Nixon nominated him on June 8, 1973. During the three days of confirmation hearings, Senators appeared satisfied that Kelley would maintain nonpartisan independence from the White House and be responsible to their concerns. The Senate Committee on the Judiciary approved the nomination unanimously the following day. He was sworn in by the President on July 9, 1973. Kelly remained FBI Director until his retirement on February 23, 1978. Frank M. Johnson Jr. With the anticipated retirement of Clarence Kelley, President Jimmy Carter nominated U.S. District Court Judge Frank M. Johnson Jr. of Alabama, on September 30, 1977. Johnson faced serious health problems around the time of his nomination, however, and the President withdrew the nomination on December 15, 1977. William H. Webster. In the aftermath of the withdrawn Johnson nomination, President Carter nominated U.S. Court of Appeals Judge William H. Webster to be Director on January 20, 1978. Prior to his service on the U.S. Court of Appeals for the Eighth Circuit, Webster had been U.S. Attorney and then U.S. District Court Judge for the Eastern District of Missouri. After two days of hearings, the Senate Committee on the Judiciary unanimously approved the nomination and reported it to the Senate. The Senate confirmed the nomination on February 9, 1978, and Webster was sworn in on February 23, 1978. He served as Director of the FBI until he was appointed as Director of the Central Intelligence Agency (CIA) in May 1987. William S. Sessions. On September 9, 1987, President Ronald W. Reagan nominated William S. Sessions, Chief Judge of the U.S. District Court of Western Texas, to replace Webster. Prior to his service on the bench, Sessions had worked as chief of the Government Operations Section of the Criminal Division of the Department of Justice and as U.S. Attorney for the Western District of Texas. Following a one-day hearing, the Senate Committee on the Judiciary unanimously recommended confirmation. The Senate confirmed the nomination, without opposition, on September 25, and Sessions was sworn in on November 2, 1987. From 1973 through 2013, Sessions was the only FBI Director removed from office. President William J. Clinton removed Sessions from office on July 19, 1993, citing "serious questions ... about the conduct and the leadership of the Director," and a report on "certain conduct" issued by the Office of Professional Responsibility at the Department of Justice. Some Members of Congress questioned the dismissal, but they did not prevent the immediate confirmation of Sessions's successor. Louis J. Freeh. President Clinton nominated former FBI agent, federal prosecutor, and U.S. District Court Judge Louis J. Freeh of New York as FBI Director on July 20, 1993, the day following Sessions's removal. The Senate Committee on the Judiciary held one day of hearings and approved the nomination. The nomination was reported to the full Senate on August 3, and Freeh was confirmed on August 6, 1993. He was sworn in on September 1, 1993, and served until his voluntary resignation, which became effective June 25, 2001. Robert S. Mueller III. On July 18, 2001, President George W. Bush nominated Robert S. Mueller III to succeed Freeh, and he was confirmed by the Senate on August 2, 2001, by a vote of 98-0. Mueller served as the U.S. Attorney for the Northern District of California in San Francisco, and as the Acting Deputy U.S. Attorney General from January through May 2001. The former marine had also been U.S. Attorney for Massachusetts and served as a homicide prosecutor for the District of Columbia. Under President George Bush, Mueller was in charge of the Department of Justice's criminal division during the investigation of the bombing of Pan Am Flight 103 and the prosecution of Panamanian leader Manuel Noriega. From 1973 through 2013, Mueller was the only FBI Director to be appointed to more than one term. P.L. 112-24 , enacted on July 26, 2011, allowed the incumbent Director to be nominated for, and appointed to, an additional two-year term. After the bill was signed, Mueller was nominated for this second term by President Barack Obama, and he was confirmed the following day by vote of 100-0. Mueller's two-year term expired on September 4, 2013. The legislative circumstances surrounding Mueller's reappointment are further detailed in Appendix A . Notably, the law passed by Congress to extend Muller's tenure raised legal questions that might arise again in the event of a similar situation. In view of this possibility, Appendix B discusses precedent for lengthening the tenure of an office and the constitutionality of extending the tenure of the directorship for the current incumbent. It further addresses whether it would have been necessary for Mueller to be appointed a second time and be subject to Senate confirmation hearings under such circumstances, given that an earlier version of the Senate bill would have allowed a two-year term without confirmation. James B. Comey Jr. As Mueller's unique two-year term drew to a close, President Obama nominated James B. Comey Jr. to succeed him. Comey had previously served as United States Attorney for the Southern District of New York, from January 2002 to December 2003, and as Deputy Attorney General, from December 2003 to August 2005. The President submitted Comey's nomination on June 21, 2013. The Senate Committee on the Judiciary held a hearing on the nomination on July 9 and voted unanimously to report the nomination favorably to the full Senate on July 18. The Senate confirmed the nomination by a vote of 93-1 on July 29. Comey began his 10-year term of office on September 4, 2013. U.S. Congress. Senate. Committee on the Judiciary.
