On Tuesday, federal authorities say they disrupted an alleged plot to attack President Donald Trump's UFC event at the White House, prompting Elon Musk and others to react on social media.

FBI Says Alleged Plot Involved Drones, Firearms And White House Event According to documents unsealed Tuesday, investigators uncovered discussions among roughly 20 individuals who allegedly planned to target the UFC Freedom 250 event held on the White House South Lawn.

Authorities said participants exchanged maps, aerial images and messages discussing escape routes, safe houses and the potential use of drones carrying explosives.

Investigators also recovered multiple high-powered firearms during the probe.

The FBI said it learned of the alleged threat on June 10, four days before the event.
