Former Florida Rep. Alan Grayson (D) on Wednesday blasted Republicans in Congress for continuing to grill U.S. Attorney General Eric Holder over the “fast and furious” gun-running scandal.

"Why won't they launch an investigation of why 50 million Americans don't have health care?" he asked on Current TV. "When are we going to see those investigations?"

Republicans on the House Oversight Committee chose to hold Holder in contempt of Congress over the Department of Justice’s refusal to release certain documents pertaining to the failed operation.

Grayson said the documents requested by Republicans could put law enforcement official at risk if released publicly. He described their investigation as a "circus" that was solely intent on harming the Obama administration.

"I think it is already back firing on them," he said. "People are fed up with the Republicans. They understand the only thing they care about are tax cuts and giving the President a hard time -- and I'm talking about tax cuts for the one percent."
