(CNN) -- Federal prosecutors charged two men with plotting a "killing spree" against African-Americans that would have been capped with an attempt to kill Sen. Barack Obama while they wore white tuxedos, federal officials said Monday. Paul Schlesselman, left,  and Daniel Cowart said they planned to kill more than 100 African-Americans. The U.S. attorney's office in Jackson, Tennessee, said Daniel Cowart, 20, and Paul Schlesselman, 18, were self-described white supremacists who met online through a mutual friend. Both men have been charged with illegal possession of a sawed-off shotgun, conspiracy to rob a federally licensed gun dealer and making threats against a presidential candidate.
