Federal authorities arrested multiple people in connection with an alleged plot to target the Ultimate Fighting Championship event at the White House, thwarting an attack that court documents say would have involved drones, explosive devices and multiple gunmen.At least five people have been charged in connection with the alleged plot, including 19-year-old Tycen Proper, Abraham Hermosillo Alvarez, Bryan Omar Roa, Michael Alan Thomas and Daniel K. Eskridge. The suspects spanned the country, living in states including Missouri, Ohio and California.Court documents allege a sprawling plan to attack the June 14 event attended by President Donald Trump and top Cabinet officials, including Vice President JD Vance, Secretary of State Marco Rubio, Pentagon chief Pete Hegseth and FBI Director Kash Patel.The plot unraveled on June 11 when Proper's mother went to police with concerns about her son's behavior online, recent firearms purchases and plans to travel, according to a criminal complaint. Local authorities passed the information to federal investigators, who said they combed through an online chat rife with detailed plans to attack the event on the White House lawn, including maps, escape routes and a possible "safe house."Investigators say the suspects planned to stage a demonstration outside the White House and detonate explosive-laden drones outside the event, forcing the crowd to evacuate. Multiple suspects intended to act as snipers and target top officials and wealthy guests as they fled the event, court records say.Authorities did not describe a specific motivation for the attack. Proper told investigators that the plot was designed to "jumpstart" a revolution in the U.S. Proper's mother told authorities the people her son had interacted with online claimed to be "ex-military" and "Christian-based." She added that they expressed "ultra-religious and antigovernment sentiments, specifically citing grievances about government corruption, the handling of the Epstein files, data centers taking up all the water in communities, and other government actions," according to a criminal complaint.Attempts to reach the suspects or their lawyers were unsuccessful.Read court documents about the alleged plan below.This story has been updated to add new information.Contributing: Jeanine Santucci and Josh Meyer
