Democratic presidential candidate and former Secretary of State Hillary Rodham Clinton, laughs out loud after Rep. Martha Roby, R-Ala., asked Clinton if she was home alone during night of the 2012 Benghazi attacks during testimony on Capitol Hill in Washington, Thursday, Oct. 22, 2015, before the House Select Committee on Benghazi. After laughing out loud, Clinton said it was a bit of levity at 7:15 p.m., more than nine hours since the hearing began. She described conversations with other officials and said, "I did not sleep all night." (AP Photo/Jacquelyn Martin)
