WASHINGTON (CNN) -- Two self-described white supremacists pleaded not guilty Thursday to charges they plotted to kill now-President-elect Barack Obama in the days before the election, federal prosecutors said.

Paul Schlesselman, left, and Daniel Cowart are accused of planning to kill more than 100 African-Americans.

Daniel Cowart, 20, and Paul Schlesselman, 18, appeared Thursday for arraignment before a U.S. magistrate in Memphis, Tennessee.

A spokeswoman for the U.S. attorney's office said no trial date for the two has been set.

A grand jury indicted both men on charges of illegally possessing a sawed-off shotgun, conspiracy to rob a federally licensed gun dealer and making threats against a presidential candidate, authorities said.

Prosecutors allege they plotted a "killing spree" against African-Americans and hoped to cap their rampage with an assassination attempt against Obama.

According to court documents, Cowart and Schlesselman planned to kill more than 100 African-Americans, including 14 who would be beheaded.
