State Department officials on an emergency conference call during the Benghazi attack brought up concerns about whether Marines that might have been deployed should wear uniforms — something officials previously said could hurt diplomacy in the region, according to House Benghazi investigators.

The final GOP-authored House Benghazi report released Tuesday included new details of a two-hour video teleconference call the night of the attack, a session led by White House Chief of Staff Denis McDonough. Clinton and top Defense officials were also on the call, which was supposed to center on how to get Americans out of harm's way.

But a substantial part of the discussion, GOP investigators said, centered on how and why the attack happened rather than narrowly examining potential rescue plans. Half of the action items people wrote down in the meeting didn't have to do with evacuation; many of them were about an anti-Islam video, which the administration would incorrectly blame for the violence.

The report also found that a State official brought up a question about whether Marines should wear civilian clothing instead of their uniforms. Under secretary of State for management Patrick Kennedy told investigators he wanted to ensure that security was enhanced, not hurt by flags on the uniforms of any U.S. military presence.

But, one commander told the committee that as they were readying themselves to deploy they kept having to change in and out of their uniforms four times.

The military never deployed to Benghazi.

State Department deputy spokesperson Mark Toner in a statement said the clothing issue did not affect the speed or timeliness of any possible military response.

“We are aware that the committee is critical of these issues, but we are not aware of any finding that they had any impact on the attacks or our ability to send help," the statement says. "The fact is, we did not cause a delay.... Concerns about what they wore had no bearing on the timing of their arrival.”
