Bloomberg reports:
FBI Director James Comey signaled he has no plans to resign despite once again being at the center of a political storm — this time over probes into Russian hacking of the 2016 election and his request that Justice Department officials reject President Donald Trump’s claims that his predecessor “tapped” his phones.
“You’re stuck with me for about another six and a half years,” Comey said Wednesday at a cybersecurity conference in Boston, referring to the time remaining in his 10-year appointment to the post.
While Trump publicly praised Comey days after his inauguration, saying “he’s become more famous than me,” the president has also lashed out at the FBI over “leakers” he says are undermining his administration. He’s also criticized findings by the intelligence community, including the FBI, that Russia interfered in last year’s election.
From Wikipedia:
The FBI Director is appointed by the President and confirmed by the Senate. J. Edgar Hoover, appointed by Calvin Coolidge to the predecessor office of Director of the Bureau of Investigation in 1924, was by far the longest-serving director; he held the position from its establishment under the current title in 1935 until his death in 1972.
In response to Hoover’s lengthy tenure, Congress imposed a term limit of ten years for future directors, which was waived by the Senate for Robert Mueller on July 27, 2011 due to serious security concerns at that time.
In theory, they serve ten-year terms unless they resign, die, or are removed, but in reality, since J. Edgar Hoover, none have served a full ten years, except Robert Mueller, who served twelve years.
