President Obama’s handling of the Benghazi terrorist attack testifies either to his refusal to be transparent with Congress or a “pre-9/11 mentality” that treats terrorists as criminals, according to a top Republican.

The FBI has refused to give Congress access to transcripts of their interviews with the Benghazi attack survivors. “This is an ongoing criminal investigation is what they told me,” Sen. Lindsay Graham, R-S.C., said on Fox News Sunday. “And here’s what was really stunning, the FBI interviewed the survivors, two days after the attack in Germany and, the CIA never called the FBI for weeks, wanting the results of the interview before they made their assessments — we are going back to the pre-9/11 mentality of — where we treat it as a law enforcement function, and FBI and the CIA never talk to each other, which is very dangerous.”

Obama denied last week that he has not given enough information to lawmakers. “We’ve had more testimony and more paper provided to Congress than ever before, and, Congress is sort of running out of things to ask,” he said during a Google+ hangout.
