FILE – In this June 29, 1972, file photo reporters stand in an attempt to get President Richard Nixon's attention during a White House news conference in Washington during which Nixon said he'd sign legislation banning Saturday night specials. Nixon called the news conference about six weeks after the shooting of George Wallace. Later that year the Senate did pass such a bill, but the House never acted on the legislation. Few presidents in modern times have been as interested in gun control as Nixon. (AP Photo/File)
