COLUMBUS, Ohio (AP) — Two of the eight men indicted on murder and terrorism conspiracy charges for their alleged roles in a thwarted drone and sniper attack on the UFC cage-fighting show at the White House last month pleaded not guilty Thursday.Tycen Proper, 19, of Danville, Ohio, and Chandler Scaggs, 21, of Chapmanville, West Virginia, entered the pleas before U.S. District Court Judge Edmund Sargus Jr. in Columbus, Ohio. Each is charged, as are the six others, with conspiracy to provide material support to terrorists and conspiracy to commit murder on federal government territory and to murder a federal government official.Sargus set their trial date for Sept. 14. “What would have happened or could have happened, that’s never going to be clear, because, thank God, there was an intervention here and this thing was disrupted,” U.S. Attorney Dominick Gerace II told reporters last week as he detailed the group’s July 9 indictments. “But, in my view, when I look at what’s been alleged there, it seems pretty likely that someone or multiple people were driving to Washington, D.C., to do something.”A message seeking comment was left with Proper’s attorney. Scaggs’ lawyer declined to comment.
