Washington (CNN) -- In testimony that sharply contradicted the Obama administration's initial narrative of the September 11, 2012, terrorist attacks in Benghazi, Libya, three witnesses shared firsthand accounts this week of what happened before, during and after the attack.

The three testified before the House Oversight and Government Reform Committee, recounting the horrific events that took the lives of four heroic Americans that day at the U.S. Consulate. Much of what we have known about Benghazi to this point has come from Obama administration sources. The accounts of these brave witnesses raise troubling questions about the veracity of what we've been told by official sources since the attack took place.
