"Is the program still active?"
That's just one of six questions that 14 Republicans on the House Judiciary Committee are posing to in the ATF "Gunwalking" scandal.
As a CBS News investigation has reported, current and former ATF agents say the agency intentionally allowed thousands of assault rifles and other weapons to cross the border into Mexico as part of a controversial plan to gain intelligence. Insiders refer to it as letting guns "walk."
Two assault rifles ATF allegedly allowed to walk turned up at the murder of Border Patrol Agent Brian Terry last December. Suspects arrested in the murder of Immigration agent Jaime Zapata two months later were already under surveillance by ATF.
Holder's office at first vehemently denied ATF has ever knowingly allowed weapons to get into the hands of suspected gunrunners for Mexico's drug cartels. However, when asked about it at a briefing yesterday, Holder didn't repeat the denial. Instead, he said the questions have to be taken seriously.
