Dennis William Mahon (born August 29, 1950) is an American far-right terrorist who is part of the radical white supremacist movement.
[a] The Mahon twins first got involved in white supremacist activism in the 1970s when they joined the Knights of the Ku Klux Klan.
Mahon claimed that he was inspired to join the Klan after he had read The Turner Diaries during a time when he was working as an aircraft mechanic in Florida.
Journalist Molly Conger notes he was likely further radicalized while working as a member of the Florida National Guard during the Mariel boatlift, which Mahon frequently discussed negatively.
[6] While Mahon was not charged for any activities during this time, he claimed on wiretapped calls to have set off pipe bombs and destroyed transformers.
Mahon's twin brother provided a copy of the issue to an Atomwaffen Division splinter group attempting to archive white supremacist literature.
[12] Mahon, Metzger, and his attorney appeared on the September 1, 1988, episode of The Oprah Winfrey Show where they debated the Kansas City Public Television controversy with C. T. Vivian, Emanuel Cleaver, and an Orthodox rabbi.
[17] Rogers sued for copyright infringement over the use of his theme song and Mahon signed the settlement agreement on behalf of the Klan.
Mahon claimed he encouraged German recruits to firebomb buildings occupied by foreigners and that he trained them in guerilla warfare.
[25] In 1991 Mahon held a rally in Tulsa in support of the then-president of Iraq Saddam Hussein and to protest the ongoing Persian Gulf War.
[35] Mahon was called to appear before a grand jury in Tulsa, Oklahoma in July 1997 and was to answer questions in relation to the bombing.
One witness claimed to have seen Mahon sitting next to Timothy McVeigh in the Ryder truck that contained the bomb used in the attack around 30 minutes before the explosion.
[36][37] In a 2001 interview with Jon Ronson, Mahon acknowledged meeting McVeigh at a Tulsa gunshow and praised his actions, but denied involvement in the bombing.
[42][46] After a five-year undercover federal investigation, the Mahon brothers were arrested at their Illinois home in 2009 for the connection to the 2004 Office of Diversity and Dialogue mail bombing.
