WASHINGTON — The CIA’s former deputy director said Wednesday he deleted references to terrorism warnings from widely disputed talking points on the deadly 2012 Benghazi attack to avoid the spy agency’s gloating at the expense of the State Department.

Mike Morell faced more than three hours of questioning from the House Intelligence committee in a rare open session that examined who changed the talking points — and why — in the politically charged aftermath of the deadly Sept. 11 assault on a US diplomatic mission in Libya.

Four Americans, including US Ambassador J. Christopher Stevens, were killed in two separate attacks over a chaotic period of several hours. Multiple independent and congressional investigations have largely faulted the State Department for inadequate security at the mission.


Morell, a 33-year veteran of the agency who has served six Republican and Democratic presidents, said politics had no bearing on the revisions to the talking points and said he was under no pressure to protect either President Obama or then-Secretary of State Hillary Rodham Clinton.

‘‘I never allowed politics to influence what I said or did. Never,’’ he said.

The White House, wrapped in a presidential campaign, made only minor editorial changes to the talking points, according to the ex-CIA official.

The intelligence community’s talking points, compiled for members of Congress, suggested the Sept. 11 attack stemmed from protests in Cairo and elsewhere about an anti-Islamic video rather than an assault by extremists.

Republicans have accused the Obama administration of trying to mislead the American people about an act of terrorism in the final weeks before the November election.

Morell deleted references to extremist threats linked to Al Qaeda in versions of the talking points used by Susan Rice, then US ambassador to the United Nations, in a series of Sunday talk show appearances. Morell said his actions were driven by the information provided by intelligence community analysts and the Defense Department.


He said the CIA knew that some of the individuals in the attack were Al Qaeda from classified sources, information that could not be included unless it was declassified. The talking points were provided to members of the panel for dissemination to the American people.

Morell said he removed references to the warnings based on previous CIA analysis. Otherwise, he said, the talking points would have been a ‘‘way for CIA to pound its chest and say ‘we warned,’ laying all the blame on the State Department.’’

Morell said there would be plenty of time later on to figure out what went wrong.

In his prepared testimony, Morell said he was deeply troubled by allegations made by lawmakers and some in the media ‘‘that I inappropriately altered and influenced CIA’s classified analysis and its unclassified talking points about what happened in Benghazi, Libya in September 2012 and that I covered up those actions.’’

‘‘These allegations accuse me of taking these actions for the political benefit of President Obama and then Secretary of State Clinton. These allegations are false,’’ Morell said.

He said he and the agency could have done a better job, but he dismissed suggestions that the CIA ‘‘cooked the books’’ in the assessment of the attack.

Morell said he had no idea that Rice would use the talking points on the Sunday shows.

Morell described his step-by-step actions, from the first time he saw the talking points on Friday, the 14th, to his concerns about the inclusion of warning language. He said an intelligence analyst on the 13th had said the attack evolved spontaneously from a protest.
