WASHINGTON (AP) - The Senate is expected to confirm James Comey to head the FBI, despite a leading conservative's demands for more information on the Obama administration's domestic use of drones. Senators planned to vote Monday on whether to block delaying tactics against Comey's nomination. Lawmakers were expected to end those delays, with final approval of his nomination likely late Monday or Tuesday. President Barack Obama nominated Comey in June to succeed Robert Mueller, whose 12 years as FBI director are expiring. Comey was the No. 2 Justice Department official under President George W. Bush a decade ago. He attracted attention for fighting Bush White House demands for warrantless wiretapping. Kentucky Republican Sen. Rand Paul has been threatening to block Comey's nomination until the FBI provides more information on its use of drones.
