Republicans have been highly critical of "Operation Fast and Furious," a federal operation that lost track of firearms purchased by suspected gun smugglers. Some of the weapons have turned up in the wake of shootings in Mexico.

At a Congressional hearing yesterday, ATF agents said they tried to blow the whistle on the operation. Evan Perez covers the Justice Department for the Wall Street Journal.
