WASHINGTON (CBS DC) — Sen. Lindsey Graham, R-S.C., says the Republican-led House report into the 2012 Benghazi attacks – which said the CIA and the military responded properly to attack on the U.S. diplomatic compound – “is full of crap.”

The Republican-led Benghazi report found there were no outright intelligence failures, no delay in attempts to rescue staff of the U.S. consulate and no political cover-up – although the report described a “flawed” process used by then-U.N. Ambassador Susan Rice to form talking points in the aftermath of the 2012 attacks.

The House Intelligence Committee report debunked a series of continued allegations that suggested dark conspiracies and long-term cover-ups surrounding the Obama administration’s handling of the attack. The report was released with little fanfare on the Friday before Thanksgiving week.

But Graham, one of the most outspoken critics of the Obama administration’s handling of Benghazi, dismissed the House report along with the series of previous GOP-led probes into the 2012 attack.

“I think the report is full of crap, quite frankly” Graham told CNN’s “State of the Union” on Sunday, adding that the intelligence community “lied” through then-deputy director of the Central Intelligence Agency, Mike Morell.

“I don’t believe that the report is accurate, given the role that Mike Morell) played in misleading the Congress on two different occasions,” said Graham. “Why didn’t the report say that?”

“Only later did we find out through a lawsuit that Mike Morell was deeply involved in changing the talking points, the deputy director of the FBI. When he was sitting in front of a congressional panel… Graham continued. “And he was asked, does anybody here know who changed the talking points, he sat silent. So, no, the intel community through him lied.”

Graham refused to exonerate the Obama administration’s response despite the report’s vindication of its actions, instead saying he is doing to do his own “hard review” of the report.

“I’m saying that anybody who has followed Benghazi at all knows that the CIA deputy director did not come forward to tell Congress what role he played in changing the talking points,” said Graham. “And the only way we knew he was involved is when he told a representative at the White House, I’m going to do a hard review of this, a hard rewrite.”

“The question was not how you gathered intel. Who changed the talking points? It went through several changes. Who came out with the version most politically beneficial to the administration?”

Many of the report’s findings echo those of six previous investigations by various congressional committees and a State Department panel in addition to the eighth Benghazi investigation being carried out by a House Select Committee appointed in May.

But Graham insisted much of the Benghazi issue centers around the fact the attacks took place just prior to the 2012 presidential election and was used for political gain.

“Three days after the attack, they did not give a damn about the intelligence. They wanted to create a political narrative to protect the president,” said Graham. “And I’m not going to stop until someone is held accountable for allowing it to be a death trap, somebody be fired for not coming to the aid of these people for nine-and-a-half-hours. And somebody ought to be fired for lying to the American people. They were worried about the reelection, not telling the truth.”

The attacks in Benghazi killed U.S. Ambassador Christopher Stevens, foreign service officer Sean Smith, and two CIA contractors, Tyrone S. Woods and Glen Doherty. Ahmed Abu Khatalla, a Libyan extremist, is facing trial on murder charges after he was captured in Libya and taken to the U.S.
