Smiling suspect stands out as authorities release mugshots of 5 accused in alleged White House UFC attack plot

Authorities have released all five mugshots of the suspects, including one who was all smiles, accused of plotting what prosecutors described as a "mass casualty event" targeting President Donald Trump and other high-profile officials during the UFC Freedom 250 event at the White House, making all five booking photos publicly available.

The men were arrested this month as part of a multi-state operation after federal authorities uncovered what prosecutors allege was a coordinated attack plan involving explosive-laden drones, sniper teams and safe houses intended to support an assault during the event.

U.S. Attorney for the District of Columbia Jeanine Pirro told Fox News on Wednesday that her office is not handling any portion of the case despite the alleged plot targeting a White House event.

"We do not have a piece of that case," Pirro said.

Asked whether she expected the matter could eventually be brought to her office because the alleged target was in Washington, D.C., Pirro said prosecutors need activity within the district to establish jurisdiction.

"You have to have some kind of actual activity to bring a case," Pirro said.

Fox News Digital obtained all five booking photos.
