The push to get Rep. Alan Grayson (D-Fla.) named to the House Select Committee on Benghazi is getting a boost from the second-largest online progressive advocacy group, Credo Mobilize.

The suggestion was first made in The American Prospect, with author and SiriusXM host Ari Rabin-Havt arguing that instead of boycotting the committee, Democrats appoint a legislator who will go unabashedly to battle with Republicans.

"The pugnacious former litigator has demonstrated the exact skill set needed to cut through the Republican mythology, the work ethic necessary to fully immerse himself in the issue, and the temperament to weather the blistering attacks sure to come from the conservative media," Rabin-Havt wrote.

A Credo Mobilize petition is urging House Minority Leader Nancy Pelosi (D-Calif.) to appoint Grayson as the sole Democratic member on the committee.

"In the aftermath of the Iraq War, Grayson’s courtroom prowess resulted in millions of dollars in judgments against war profiteers. This skill was on display in September when the congressman used his five minutes as a member of the Foreign Affairs Committee to dismantle conservative Benghazi mythology while questioning Undersecretary of State Patrick Kennedy," Rabin-Havt added.

House Democrats have yet to reach a final decision on whether or not they will participate in the committee, which they contend is nothing more than a political "witch-hunt."
