Last week, in an interview with Fox News Channel’s Bret Baier, Senator Lindsey Graham (R-SC) called out House Republican leaders for not forming a House Select committee or issuing subpoenas to survivors of the Benghazi attacks. Now, in an interview with Greta van Susteren, Graham ratcheted up the pressure on House leaders again, even naming Speaker John Boehner specifically this time.

Attention turns toward Boehner’s responsibility for getting to the bottom of Benghazi at about the 3:00 mark.

“Unsung Davids”, a new and powerful book tells the story of ten modern-day heroes who fought tyranny and evil but are given little or no recognition. Click Here for more details.

Here’s a relevant portion of the exchange:

VAN SUSTEREN: Everyone writes letter in this town. Letters never get answered unless you’re in the majority party.

GRAHAM: There you go. And my Democratic colleagues in the Senate have shown no interest in getting to the bottom of Benghazi. If this were Bush they’d be all over it. The one thing Republicans can do is use the leverage they have in the House to subpoena these survivors so we’ll find out what happened that night. I guarantee you there are people wanting to talk, but are afraid to talk, and a subpoena would make a difference.

VAN SUSTEREN: Are you going to do anything, encourage the House to do that?

GRAHAM: I’m going to meet with the House leadership tomorrow, hoping they will take up the Benghazi cause. Look how far we’ve come from what the story was told by Susan Rice. Look what we found out by pushing on this show and other shows, CBS and mainly FOX. The whole scenario told by the president and Susan Rice has absolutely collapsed.

VAN SUSTEREN: Why hasn’t the House leadership —

GRAHAM: I have no idea.

VAN SUSTEREN: Why the Republican House leadership hasn’t been —

GRAHAM: To my House colleagues, please, for God’s sake step up your game when it comes to Benghazi. You have tools I don’t because I’m in the minority party in the Senate. Unfortunately Harry Reid hasn’t looked to push the administration. Look what we did on Iraq and interrogation techniques gone bad under t the Bush administration. The Democratic senators have given the president a pass when it comes to Benghazi. The House cannot give him a pass.
