Two men pleaded not guilty on Thursday to federal charges stemming from their alleged attempt to attack and storm the high-profile UFC fight at the White House last month by using drones and snipers.

Tycen Proper, 19, of Ohio, and Chandler Scaggs, 21, of West Virginia, are two of the eight defendants charged with conspiracy to provide material support to terrorists and conspiracy to commit murder on federal government territory and to murder a federal government official, as laid out in the indictment.
