Hillary Clinton said Wednesday that she has no regrets about leaving State Department headquarters during the 2012 Benghazi raid that left four Americans dead, a decision that exposed her to criticism during years of investigations into the terror attack.

"You know, I was there until 9, 10 o'clock. We had done a number of what are called SVTC’s, you know, satellite conferences," Clinton told radio host Hugh Hewitt during an interview that aired Wednesday. "I had talked on the phone. I had talked over satellite with our team in Libya. I had talked with members of our government, Defense and Intel and others, obviously the White House."

Clinton has taken fire for going home relatively early on the night of the Sept. 11, 2012 attack on a U.S. consulate in Libya. Four Americans died in the attack, and the Obama administration came under intense scrutiny for initially blaming the attack on an inflammatory YouTube clip before acknowledging that it was a planned attack.

"You know, we knew that our goal was to find all of our people and get them out of there, and that was ongoing. And so you know, I went home for a few hours of sleep. I talked to the President, bringing him totally up to date, and then obviously, you know, headed back early the next morning," Clinton said.

Asked if staying later would have made a difference, Clinton said, "I doubt it."

"That was never the principal charge that the Republicans and others made against me, and those in the administration," Clinton said. "So I don’t think that silenced the critics, because there seem to be a calculation that this was an issue that they could make political."

Clinton has been back in headlines after months of silence due to a tour to promote her 2016 campaign memoir. Her book tour will end in December.
