On the night of Dec. 14, 2010, U.S. Border Patrol agent Brian Terry was shot and killed while on patrol in an Arizona canyon near the U.S.-Mexico border. Two guns found at the scene were linked to an investigation being run by the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) called “Operation Fast and Furious,” sparking a congressional inquiry into the program and generating considerable criticism of the ATF and the Obama administration. Because of this criticism, in August 2011 ATF acting director Kenneth Melson was reassigned from his post and the U.S. attorney for Arizona was forced to resign.

Currently, the congressional inquiry is focused on U.S. Attorney General Eric Holder, who has been accused of misleading Congress about what he knew about Fast and Furious and when he learned it. The Obama administration has invoked executive privilege to block the release of some of the Department of Justice emails and memos sought by Congress pertaining to the operation. The controversy escalated June 28 when the U.S. House of Representatives voted to hold Holder in contempt of Congress for ignoring its subpoenas. read more
