Leave it to journalists outside the U.S. to provide more stunning details about U.S. Attorney General Eric Holder's botched "Fast and Furious" gun tracking program.

The Spanish network Univision dropped a bombshell over the weekend, releasing an in-depth report directly tracing the guns used in the attempted operation to at least two significant massacres that occurred in 2009 and 2010. Using information obtained from a Mexican Army report, along with what data has already been released via the U.S. government, Univision reporters found 57 more Fast and Furious guns used in crimes -- guns not reported by Congress.

The Fast and Furious operation was an attempt to use weapons smuggled across the border to lead ATF and other U.S. agents to the top of crime and drug organizations in Mexico. The light was not shed on the plan until a gun that was "allowed" to be purchased illegally by a drug ring was used to kill U.S. Border Patrol Agent Brian Terry. Univision claims 1,961 guns were allowed to trickle over the border, and they were used in the now-infamous January 2010 massacre of 14 people at a college/high school birthday party in Villas de Salvacar, Ciudad Juarez. Some 20 armed men sped up to the function, attended by nearly 60 people, and began gunning down victims, even chasing some down the street. It is still not specifically known exactly how many of the guns were lost to the drug cartels, but some estimate hundreds. Each month, new weapons seized in drug raids find additional guns traceable back to "Fast and Furious."

The massacre gained world-wide attention,  but not until now was it claimed that some of the weapons came from "Fast and Furious." Numerous pieces of evidence now indicate Holder reportedly knew of the operation,  and there has been calls for his resignation. He was held in contempt by Congress for refusing to turn over many documents related to the case.

President Obama still sticks to his claim that it was an 'in-field' operation that was created by lower or mid-level officials, and when Holder found out about it, he stopped it. (Video courtesy of Univision)
