The Senate Intelligence Committee released a report Wednesday on the deadly 2012 assault on the diplomatic compound in Benghazi, Libya, laying blame on the State Department, the intelligence community and even the late Ambassador Chris Stevens — who was killed in the attack along with three others — for failing to communicate and heed warnings of hostile activity in the area.

The highly critical report said the U.S. military was not positioned to aid the Americans in need, though the head of Africa Command had offered military security teams that Stevens had rejected weeks before the incident.

The report also said that in the aftermath of the attack, U.S. analysts confused policymakers by blaming the violence on protests without enough supporting intelligence.

There was no immediate comment from the State Department.

The Benghazi attack has dogged the Obama administration because then-U.N. Ambassador Susan Rice initially blamed the violence on mob protests over an anti-Islamic film. Al-Qaeda-linked militant groups were later blamed for the strikes, first when militants overran the temporary U.S. mission on Sept. 11, 2012, and later that same night, when militants fired mortars at the nearby CIA annex where the Americans had taken shelter.

The bipartisan report may settle what has become a running political battle between many Republicans — who say the Obama administration has been covering up alleged misdeeds before, during and after the attack – and the administration, which says Republicans are on a political witch hunt.

Intelligence Committee Chairman Dianne Feinstein, D-Calif., said she hopes the report will put to rest conspiracy theories about the militant attacks that night. Georgia Republican Saxby Chambliss, vice chairman of the committee, said the report shows that despite a worsening security situation in Benghazi, the U.S. government did not do enough to prevent the attack or to protect the diplomatic facility.

"The State Department should have increased its security posture more significantly in Benghazi based on the deteriorating security situation on the ground and IC (intelligence community) threat reporting on the prior attacks against Westerners in Benghazi — including two previous incidents" at the temporary diplomatic facility that year, the report said.

It added that "tripwires" set to determine when it had become too dangerous to operate in Benghazi were crossed, but ignored, by both the U.S. and other nations.

The Defense Department had provided a site security team in Tripoli, made up of 16 special operations personnel, to provide security and other help. The State Department, according to the report, decided not to extend the team's mission in August 2012, one month before the attack. In the weeks that followed, Gen. Carter Ham, the head of Africa Command, twice asked Stevens to employ the team, and twice Stevens declined, the report said.
