The FBI has thwarted an alleged plot targeting President Trump’s UFC America 250 event at the White House, according to a federal criminal complaint and affidavit released by law enforcement officials.
FBI Director Kash Patel stated that the threat first surfaced on June 10, prompting rapid action by the Bureau and partner agencies. The multi-state operation resulted in multiple individuals being taken into custody, with investigators reporting the alleged attacks were “stopped cold.”
The affidavit details that Tycen Proper engaged in extensive online communications via Signal groups. Investigators found evidence that Proper had become increasingly isolated from his family, posting sympathetic comments about Adolf Hitler and anti-Semitic content on social media platforms.
On June 11, 2026, law enforcement executed a search warrant on Proper’s seized Apple iPhone. The device contained detailed tactical plans for an attack during the UFC event scheduled for June 14, 2026. These plans included:
– Deployment of small unmanned aircraft (drones) carrying explosive devices to detonate near the White House lawn.
– Staged demonstrations designed to create chaos and force attendees and high-value targets to evacuate southward.
– Designated snipers positioned along the evacuation route to target fleeing individuals.
The affidavit reveals that Proper was part of an online group called “Vanguard of the Old,” which operated on TikTok. Members of this group, including Proper, believed the United States was headed in the wrong direction and needed to be torn down for rebuilding. Some expressed a desire that individuals associated with Jeffrey Epstein should not hold political office.
The group had a tiered structure, with “Tier 1” members required to meet physical fitness standards and acquire body armor and firearms. Proper admitted to being one of the team leaders in planning the attack, which he described as designed to “jumpstart” a revolution in the United States.
According to the affidavit, a California man named Michael Alan Thomas was identified as one of the alleged organizers.
Law enforcement recovered evidence from Proper’s phone showing a primary Signal chat group with approximately 19 individuals and smaller subgroups organized by role and location. The detailed planning, including maps of the Capitol Region and specific tactical instructions, indicates a coordinated effort rather than an informal threat.
The criminal complaint lists four alleged offenses: conspiracy to commit a federal felony, attempted murder of a federal officer or employee, possession of a firearm in furtherance of a crime of violence, and receipt or transfer of a firearm used in a felony.
Proper is currently charged with these crimes.
