WASHINGTON, D.C. ­– Unable to suppress her excitement, a giddy Secretary Hillary Clinton sat before the Select Committee on Benghazi Thursday to give a testimony once again on the September 11, 2012 attacks, a day after Vice President Joe Biden announced that he would not seek the 2016 Democratic nomination for President. On Thursday morning, Clinton was dropped off at the site of the hearing by a party bus rented just the night before.
