Federal prosecutors have charged five men over an alleged plot to attack the UFC Freedom 250 event on the White House South Lawn, with drones, snipers and a plan to trigger mass panic. The plot was disrupted by the FBI after encrypted messages and online chatter surfaced. The event coincided with President Trump’s 80th birthday and drew high-profile attendees. Investigators say the group discussed tearing down the United States to rebuild it.
