Top Republicans and witnesses ripped the Obama administration's response to last year's deadly attack on the U.S. diplomatic compound in Benghazi, Libya, calling key executive branch officials unresponsive in the critical hours after the assault and uncooperative in the investigations that followed.
Our goal "is to get answers because their families (of the victims) deserve answers," said California Rep. Darrell Issa, the Republican chairman of the House Oversight Committee, which heard from State Department "whistleblowers" at a hearing on Wednesday.
"The administration, however, has not been cooperative and unfortunately our (Democratic House) minority has mostly sat silent," he said.
Issa spoke prior to testimony from Eric Nordstrom, a former regional security officer in Libya; Mark Thompson, the State Department's acting deputy assistant secretary for counterterrorism; and Gregory Hicks, the former deputy chief of mission in Libya.
