(CBS News) The Justice Department's inspector general cleared Attorney General Eric Holder and his top deputies Wednesday of knowing about the gunwalking operation known as Fast and Furious that allowed thousands of weapons to cross into Mexico.
Two of those weapons turned up at the scene where Border Patrol Agent Brian Terry was killed during a shootout in 2010 with drug traffickers.
While the inspector general put most of the blame for Fast and Furious on investigators in Phoenix, one senior official, Jason Weinstein, is blamed for not acting to stop the tactics.
Weinstein resigned Tuesday night. His lawyer told CBS Radio News that the report was badly flawed.
