Benghazi Security Guard Gave Differing Accounts of Attack to CBS and the FBI

CBS News chairman says "We're surprised to hear about this, and if it shows we've been misled, we will make a correction"

Dylan Davies, a security officer hired to help protect the United States Special Mission in Benghazi, Libya, gave the F.B.I. an account of the night that terrorists attacked the mission on Sept. 11, 2012 that contradicts a version of events he provided in a recently published book and in an interview with the CBS News program "60 Minutes."
