G. Gordon Liddy, a convicted felon, served four and a half years in prison in connection with his conviction for his role in the Watergate break-in and the break-in at the office of the psychiatrist of Daniel Ellsberg, the military analyst who leaked the Pentagon Papers. Liddy has acknowledged preparing to kill someone during the Ellsberg break-in "if necessary"; plotting to murder journalist Jack Anderson; plotting with a "gangland figure" to murder Howard Hunt to stop him from cooperating with investigators; plotting to firebomb the Brookings Institution; and plotting to kidnap "leftist guerillas" at the 1972 Republican National Convention -- a plan he outlined to the Nixon administration using terminology borrowed from the Nazis. (The murder, firebombing, and kidnapping plots were never carried out; the break-ins were.) During the 1990s, Liddy reportedly instructed his radio audience on multiple occasions on how to shoot Bureau of Alcohol, Tobacco, and Firearms agents and also reportedly said he had named his shooting targets after Bill and Hillary Clinton. Liddy has donated $5,000 to McCain's campaigns since 1998, including $1,000 in February 2008. In addition, McCain has appeared on Liddy's radio show during the presidential campaign, including as recently as May. An online video labeled "John McCain On The G. Gordon Liddy Show 11/8/07" includes a discussion between Liddy and McCain, whom Liddy described as an "old friend." During the segment, McCain praised Liddy's "adherence to the principles and philosophies that keep our nation great," said he was "proud" of Liddy, and said that "it's always a pleasure for me to come on your program."
