The senior intelligence official said that CIA officers in Benghazi, "responded to the situation on the night of 11 and 12 September as quickly and as effectively as possible.
"The security officers in particular were genuine heroes. They quickly tried to rally additional local support and heavier weapons, and when that could not be accomplished within minutes, they still moved in and put their own lives on the line to save their comrades," the official said.
"At every level in the chain of command, from the senior officers in Libya to the most senior officials in Washington, everyone was fully engaged in trying to provide whatever help they could," the official said.
"There was no second-guessing those decisions being made on the ground, by people at every U.S. organization that could play a role in assisting those in danger. There were no orders to anybody to stand down in providing support," the official added.
