Attorney General Eric Holder attributed the difficulty preventing gun-trafficking into Mexico to weak gun controls laws, when he blamed on the U.S. House, with particular reference to the House investigators asking him about Operation Fast and Furious.

"ATF’s ability to stem the flow of guns from the United States into Mexico suffers from a lack of effective enforcement tools," Holder told the House Oversight and Government Reform Committee today. "Unfortunately, in 2011, a majority of House Members – including all members of the majority on this Committee – voted to keep law enforcement in the dark when individuals purchase multiple semi-automatic rifles, shotguns, and long guns – like AK-47s – in gun shops in four southwest-border states."

Holder also suggested that the political partisanship is motivating the investigation. "I am determined to ensure that our shared concerns about these flawed law enforcement operations lead to more than worn- out Washington 'gotcha' games and cynical finger pointing," he said.
