WASHINGTON » The Senate overwhelmingly confirmed James Comey today to become FBI director, elevating the one-time Justice Department official who defied efforts by President George W. Bush’s White House to renew a program that allowed warrantless eavesdropping.

Comey was approved 93-1 after one of the Senate’s leading conservatives abruptly ended delaying tactics that had blocked a vote on the nomination.

Sen. Rand Paul, R-Ky., mentioned as a possible 2016 GOP presidential candidate, had been thwarting the vote over his concerns about the FBI’s domestic use of drones. Minutes before a showdown vote that seemed likely to force an end to his delays, Paul announced he would allow a vote on Comey, saying he’d received a letter from the FBI that answered his questions about drones.

Paul was the only "no" vote.

President Barack Obama nominated Comey, 52, in June. He will succeed Robert Mueller, who is stepping down in September after 12 years heading the agency.

Comey was the Justice Department’s No. 2 official from 2003 to 2005 under Bush. He gained attention during a brief stint as acting attorney general in 2004, when he and Attorney General John Ashcroft, who was ill, rejected an effort by White House Chief of Staff Andrew Card and White House counsel Alberto Gonzales to have Justice renew a program that allowed eavesdropping without court warrants of domestic phone calls and emails.

"James Comey proved that his reputation for unwavering integrity and professionalism is well-deserved," Senate Judiciary Committee Chairman Patrick Leahy, D-Vt., said on today’s brief debate.

Leahy expressed concerns about Comey’s approval in 2005 of a legal memo that he said authorized the use of torture, including waterboarding, in which water is poured onto a suspect’s face to make them feel like they’re drowning. But Leahy cited Comey’s answers at a committee hearing this month, when Comey said the FBI would not allow abusive treatment of prisoners.

Today’s vote led off a week in which majority Democrats were hoping to push a parade of nominations through the chamber. Among them were President Barack Obama’s picks of Samantha Power as U.N. ambassador and B. Todd Jones to head the Bureau of Alcohol, Tobacco, Firearms and Explosives, for which votes on ending delaying tactics were expected Wednesday.

This is Congress’ last week before its five-week summer recess.
