Thousands packed the White House South Lawn to witness UFC cage fights Sunday night. News4's Darcy Spencer reports.

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 during a rally in Butler, Pennsylvania, and months later, when a man aimed a rifle through bushes at Mar-a-Lago, where Trump was playing golf.

Last year, a Minnesota state lawmaker and her husband were killed in what authorities called a  politically motivated  attack. The suspect, Vance Boelter, has pleaded guilty to the crime. Months after those shootings, conservative activist Charlie Kirk was shot and killed at a political event.

Lawmakers too, are facing a spike in threats. The U.S. Capitol Police said they investigated nearly 15,000  concerning statements, behaviors, and communications  targeting lawmakers, their families, staff or the Capitol last year. The prior year, police investigated more than 9,000 potential threats.
