On August 30, 2011, Burke resigned,, as a result of increased pressure being applied to his U.S. Attorney for the District of Arizona office from various directions, including Congress, in the wake of the gunwalker scandal. Project Gunrunner occurred within the ranks of the U.S. Justice Department, specifically the FBI and the BATF&E, and resulted in sweeping investigations and multiple resignations with Burke's resignation being the most senior of these. Former U.S. Attorney Dennis Burke admitted leaking a sensitive document about a federal agent who blew the whistle on the gunrunning operation. Mr. Burke’s Phoenix attorney, Lee Stein, said in a Nov. 8 2011 letter to the Justice Department’s Office of Inspector General that his client had provided information to a reporter who was working on several stories involving Fast and Furious. The family of slain U.S. Border Patrol Agent Brian Terry charged that Mr. Burke, then US Attorney for the District of Arizona, lied to them about the guns found at the crime scene in an attempt to hide the weapons' connection to the ATF's failed Fast and Furious gun sales operation. Terry was killed in December 2010, allegedly by Mexican bandits carrying at least two AK-47 semiautomatic rifles that had been purchased in Arizona as part of Fast and Furious. The operation was intended to catch drug lords using illegal weapons, but the ATF immediately lost track of 1,700 firearms. The Terry family alleged that then-U.S. Atty. Dennis K. Burke told them last March that the two weapons came from a store in Texas and were not part of Fast and Furious. The family made their allegations in a "notice of claim" stating that they intend to sue the Bureau of Alcohol, Tobacco, Firearms and Explosives and the Justice Department for $25 million. They called the gun-tracking operation "abominable, reckless, nonsensical." In May 2013, Burke was criticized by the Department of Justice Inspector General for an inappropriate leak to Fox news. On March 27, 2014, the Arizona Bar Association reprimanded Dennis Burke.
