Arizona White Supremacist Bombing Trial Set For Closing Arguments

Closing arguments are scheduled today in the trial of white supremacist twin brothers accused of sending a mail bomb in 2004 to a city diversity office in Scottsdale, Ariz., the Associated Press reports.

Brothers Dennis and Daniel Mahon, who have longtime ties to groups like the Ku Klux Klan and White Aryan Resistance, pleaded not guilty in the bombing plot.

The trial is the result of a deep undercover investigation run by agents in the Arizona office of the US Bureau of Alcohol, Tobacco, Firearms and Explosives.
