(WASHINGTON) -- The family of a U.S. border patrol agent who was fatally shot in Arizona late last year will testify before Congress Wednesday on the heels of a Congressional report showing that the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) allowed guns to be illegally purchased in the U.S. and carried into Mexico.
Two guns recovered from the scene where Brian Terry was killed were traced back to the ATF operation dubbed "Fast and Furious."
The joint House and Senate investigative report says the operation was poorly run and that the ATF knowingly allowed as many as 1,800 U.S. guns to be illegally bought by straw purchasers, with many of those firearms being bound for Mexico.
Those weapons, the report alleges, helped fuel the escalating violence and deaths in Mexico.
