(CBS NEWS) As the deputy chief of mission for the U.S. in Libya, Gregory Hicks was on the ground at the U.S. Embassy in Tripoli on September 11, 2012, when terrorists launched two attacks on American compounds in Benghazi.
Hicks and two other government officials have been named as witnesses for a Congressional hearing Wednesday before the House Oversight Committee. The others are: Eric Nordstrom, the former lead security official for the State Department in Libya, and Mark Thompson, the acting deputy assistant secretary for counterterrorism at the State Department. Other so-called "whistleblowers" from federal agencies, including the CIA, have provided information to Congressional investigators, but are said to be unwilling - so far - to speak publicly because they aren't authorized by their agencies to do so. Some claim fear of retaliation.
It's been a remarkably long period of silence from the dozens of American survivors and eyewitnesses who were in Libya the night of the attacks. It's not publicly known what testimony the witnesses will give at this week's hearing, but in a series of interviews and communications, CBS News has obtained information about some of areas of knowledge the witnesses can address.
