Congressman Frank Wolf (R-Va.) agreed, saying: "There are questions that must be asked of the CIA and this must be done in a public way."
The Agency, for its part, doesn't want anyone knowing what it was doing in the Libyan port city.
On Thursday Drew Griffin and Kathleen Johnston of CNN reported that the CIA "is going to great lengths to make sure whatever it was doing, remains a secret."
Sources told CNN that 35 Americans were in Benghazi that night — 21 of whom were working out of the annex — and that several were wounded, some seriously.
One source said: "You have no idea the amount of pressure being brought to bear on anyone with knowledge of this operation."
Among the questions are whether CIA missteps contributed to the security failure in Benghazi and, more importantly, whether the Agency's Benghazi operation had anything to do with reported heavy weapons shipments from the local port to Syrian rebels.
