Issa to face down Holder on Hill over new Fast & Furious information Attorney General Eric Holder will face his toughest accuser and antagonist on Capitol Hill on Thursday when he comes face to face with GOP Rep. Darrell Issa, who is expected to ask questions about new information regarding the Justice Department's disastrous Fast and Furious gun sting. Issa, chairman of the House Oversight Committee, released information Monday about six wiretap applications that he says prove high-ranking Justice Department officials knew about the operation's so-called "gun-walking" tactic. Issa, R-Calif., says the applications were signed by Assistant Attorney General Lanny Breuer, Holder's second in command. The Obama administration has repeatedly said high-level Justice Department officials had no specific knowledge of the gun-walking tactic. The questioning is expected when Holder testifies before the House Judiciary Committee, on which Issa is a member. Holder has testified at least seven times before Congress on the issue and has acknowledged the program's failures. "We now know ... inappropriate tactics were used in an attempt to stem the flow of illegal guns across the Southwest border," Holder is expected to say Thursday in prepared testimony. Although these law enforcement operations ... were focused on the laudable goal of dismantling illegal gun-trafficking networks, they were flawed in both concept and execution. The Justice Department responded to Issa's interpretation of the wiretap applications in a letter, saying the agency disagrees with his assertion, but is "legally prohibited from commenting on the content of sealed court documents." The gun-walking tactic had the Bureau of Alcohol, Tobacco, Firearms and Explosives in Arizona stage gun sales across the Mexico border with alleged arms dealers, with the hope that the thousands of weapons would lead to organizers of drug cartels. However, the guns purportedly were used in street crimes, and one was allegedly found after a shootout in which U.S. Border Patrol Agent Brian Terry was killed. Issa has also issued a subpoena to Holder asking him for additional documents on Fast and Furious, which ended in 2010. And he has vowed to hold Holder in contempt of Congress for not providing additional information. Holder has said he has given congressional investigators the requisite information.
