WASHINGTON – James Clapper, director of US National Intelligence, has resigned ahead of presidential transition next year.

Clapper, 75, submitted a letter of resignation to President Barack Obama on Wednesday night and made the announcement public during his opening statements before the House Intelligence Committee yesterday.

“[I] submitted my letter of resignation last night, which felt pretty good,” he said. “I have 64 days left and I’d have a pretty hard time with my wife going past that.”

His last day will be Jan. 20, the day of the presidential inauguration, the UPI reports.

As national intelligence director, Clapper has authority over agencies that include the Central Intelligence Agency, the Drug Enforcement Agency and the Federal Bureau of Investigation.

Clapper’s resignation comes as President-elect Donald Trump takes steps forward to implement his administration’s national security plans.

Several officials named as possible replacements include Rep. Devin Nunes, R-Calif., the chairman of the Intelligence Committee and a member of Trump’s transition team, and former Rep. Pete Hoesktra, R-Mich., who served on the Intelligence Committee.

Shortly after Clapper made his resignation public, Sens. James Lankford, R-Okla., and Angus King, I-Maine, urged Trump to choose a replacement quickly.

“A successful [director of national intelligence] makes the intelligence community more efficient, more collaborative, limits redundancies and advances seamless information sharing across our intelligence agencies,” they wrote in a letter to Trump.

Clapper, appointed by Obama in 2010, is the nation’s fourth director of national intelligence, a position created in the years following the Sept. 11, 2001, attacks on the United States.

He had previously served during the administrations of George W. Bush and George H.W. Bush as the under secretary of defense for intelligence and the director of the Defense Intelligence Agency, respectively.
