McCain confirms he'll attend Libya hearings after missing one

His absence from a Senate Homeland Security and Governmental Affairs Committee hearing on Wednesday raised eyebrows among some of his colleagues — including Sen. Susan CollinsSusan CollinsElection-year politics: Senate Dems shun GOP vulnerables Swing-state Republicans play up efforts for gun control laws Reid knocks GOP on gun 'terror loophole' after attacks MORE (R-Maine), the panel’s ranking member — and the White House. The former GOP presidential candidate has been a strong critic of the administration’s handling of the attack, which killed the U.S. ambassador to Libya and three other Americans.

McCain told The Hill that missing the Wednesday hearing was accidental. "It was a scheduling mistake," McCain said as he walked into the Senate Intelligence hearing. 

McCain’s office on Thursday said the senator would be in attendance at a closed afternoon  hearing with the Senate Intelligence Committee and another panel meeting on Friday with ex-CIA Director David Petraeus.

While lawmakers at Wednesday’s hearing, which McCain missed, heard details from State Department, Department of Defense, FBI and intelligence officials about the attack, Thursday’s hearing will be with higher-level officials.

Acting CIA Director Mike Morell, Director of National Intelligence James Clapper, FBI Deputy Director Sean Joyce, Undersecretary of State for Management Pat Kennedy and National Counterterrorism Center Director Matthew Olsen are all expected to testify.

McCain’s scheduling mix-up was amplified by a dust-up on Wednesday between the senator and President Obama. McCain promised to block U.N. Ambassador Susan Rice as a nominee if the administration put her forward to replace Hillary ClintonHillary Rodham ClintonWhat will be October’s surprise?

“If Sen. McCain and Sen. Graham and others want to go after somebody, they should go after me,” Obama said. “And I’m happy to have that discussion with them. But for them to go after the U.N. ambassador, who had nothing to do with Benghazi, and was simply making a presentation based on intelligence that she had received, and to besmirch her reputation, is outrageous.”
