Top Republicans blasted Attorney General Eric Holder on Tuesday after reports he might have known about the controversial “Fast and Furious” gun-tracking operation earlier than he previously claimed.

Sen. John McCain (R-Ariz.) tweeted, “What part of Q, ‘When did you first know about the program known as Fast and Furious?’ didn't AG Holder understand?”

McCain has asked for a Senate hearing into the operation.

Rep. Darrell Issa (R-Calif.), who is conducting the House inquiry as chairman of the Oversight Committee, retweeted McCain, along ! with links to news reports. Issa has used Twitter extensively to push for transparency during his committee’s ongoing investigation into the ATF operation that may have led to the death of a Border Patrol agent.

Two other Arizona Republicans, Reps. Ben Quayle (R) and Trent Franks (R) also took interest in the story. Rep. Franks tweeted a link to a conservative blogpost about Holder. The gun-running operation took place in the southwest, and has consequentially been a central issue for congressmen from that region.
