Top officials and agents from the Bureau of Alcohol, Tobacco, Firearms and Explosives faced questioning Tuesday from the House Oversight and Government Reform Committee hearing as part of the ongoing investigation into the Department of Justice's gun running sting called Operation Fast and Furious.
A new congressional report says that more than 125 firearms from that operation were discovered at drug cartel crime scenes in Mexico without the knowledge of the Mexican government.
In Fast and Furious, several agents with the ATF say they were inexplicably ordered by superiors to stop tracking some small-time "straw" buyers who purchased large numbers of weapons apparently destined for drug cartels.
Twenty low-level gun buyers have been charged in the operation.
