President Barack Obama called Republican Sens. Lindsey Graham and John McCain comments about U.S. Ambassador to the United Nations Susan Rice "outrageous" at a press conference held on Wednesday, CNN reported.
"If Senator McCain and Senator Graham and others want to go after someone they should go after me," Obama said.
Both senators have said they would work to block Rice out of becoming Secretary of State because of her recent relationship with the events in Benghazi, Libya, the Washington Post reported.
Rice had suggested the attack was a spontaneous crime, but it was later discovered that it was planned, the Washington Post reported.
Obama began the press conference with notes of bipartisanship and compromise, but quickly changed tones when Rice was brought up, the Washington Post reported.
Graham responded to the president shortly after the conference, CNN reported.
"Mr. President, don't think for one minute I don't hold you ultimately responsible for Benghazi. I think you failed as commander-in-chief before, during, and after the attack," Graham said.
