Sen. Lindsey Graham (R-SC) on Sunday defended his use of a "60 Minutes" report on the 2012 Benghazi, Libya attack that was retracted this week due to questions about the report's truth.
Graham said on CNN's "State of the Union" that he would not approach his investigation into Benghazi differently even though the British contractor cited in the report gave a different account of the night of the attack to FBI officials.
Graham said Sunday that he will continue to threaten a hold on Obama nominees in the Senate until he is able to interview State Department witnesses about the attack.
"I released two [holds] with the understanding that we're going to have a bipartisan process to interview the survivors and ask the basic questions," Graham said. "The only reason is I've been trying for a year to get the interviews without holds."
