Republican senators John McCain, Lindsey Graham and Kelly Ayotte held a news conference on Capitol Hill today to discuss the status of the investigation into the Sept. 11 terror attack in Benghazi, Libya, and the upcoming hearings on the matter. The trio called for the creation of a joint committee to investigate the attack, similar to panels that investigated 9/11, Iran-Contra, and Watergate.

Watch McCain's opening remarks:

Graham later responded to a question about speculation that President Obama will pick U.N. Ambassador Susan Rice to succeed Hillary Clinton as Secretary of State. Rice made headlines after the Sept. 11 attack in Benghazi by going on several Sunday talk shows and blaming an anti-Islam video for the incident. Graham said he is "dead set on making sure we don't promote anybody that was an essential player in the Benghazi debacle."

Near the end of the briefing, a reporter asked McCain whether the recent reports of classified documents possibly ending up in the possession of former CIA Director Gen. David Petraeus' mistress could be considered an even greater national security threat than the Benghazi attack.

McCain called it "one of the dumbest questions" he had ever heard.
