The FBI foiled an alleged plot to attack Sunday's UFC fight at the White House, FBI Director Kash Patel said in a post to X. On June 10, FBI and our law enforcement partners became aware of a potential threat to the UFC America 250 event in Washington, D.C. involving individuals outside of the National Capital Region - and thanks to the rapid action of this FBI, our partners, and the Department of Justice in a multi-state operation, multiple individuals are now in custody and allegedly planned attacks were stopped cold, Patel said in the post.

Fox News also reported that other alleged perpetrators then planned to storm the White House gate. NBC News has not confirmed the details of the alleged plot. A senior law enforcement official told NBC News that the plot was quite serious. Reached for comment, an FBI spokesperson referred NBC News to Patel's post. The Justice Department declined to comment, and the White House did not immediately provide comment. There was an enormous visible law enforcement presence in and around the White House complex over the weekend. Law enforcement officials blocked off roads, used fencing to control crowds and deployed hundreds of federal, state and local law enforcement officers to the crowd of thousands of people who were at or near the White House. The motives of the alleged planners have not been released. A string of acts of political violence and attempted attacks have rocked the country in recent years. In April, a man allegedly armed with guns and knives ran through a security checkpoint at the White House Correspondents' Dinner. The suspect, Cole Tomas Allen, pleaded not guilty to charges of attempting to assassinate the president. In 2024, Trump faced two assassination attempts when a gunman opened fire #nbcdfw #crimewatchdallas
