(CNN) -- Two men accused of plotting to kill Barack Obama and other African-Americans have been indicted on charges including making threats against a presidential candidate, federal officials said Wednesday.
Paul Schlesselman, left, and Daniel Cowart are accused of planning to kill more than 100 African-Americans.
A federal grand jury in Tennessee indicted Daniel Cowart, 20, and Paul Schlesselman, 18, on the threat charges and with illegal possession of a sawed-off shotgun and conspiracy to rob a federally licensed gun dealer.
According to court documents, Cowart and Schlesselman -- who authorities said are self-described white supremacists -- planned to kill more than 100 African-Americans, including 14 who would be beheaded.
They planned to cap the killing spree by charging at Obama with a car, firing from the windows as they went, dressed in white tuxedoes and top hats, the documents said.
The two were arrested last month. According to an affidavit from a federal agent who questioned them, they backed out of an October 21 attempt to rob a gun dealer after spotting two cars and a dog.
They shot out the window of a church on their way back to Cowart's grandfather's home in Tennessee, where they were arrested the next day, authorities said.
Federal law enforcement sources said there was no evidence that Cowart, of Bells, Tennessee, and Schlesselman, of West Helena, Arkansas, had any details of Obama's schedule.
Messages left late Wednesday for the attorneys of Cowart and Schlesselman were not immediately returned.
The two are being held without opportunity for bail.
