U.S. Senator Alex Padilla was detained and handcuffed by law enforcement after heckling DHS Secretary Kristi Noem at a press briefing regarding the ongoing Los Angeles riots — and there’s dramatic video of the incident.

Check out the clip … the California Democrat shouts he has questions for Noem, while trying to make a point about a “half a dozen violent criminals” as he’s being forcefully pushed from the room by several men.

He’s delivered to two FBI officers who were assisting the Secret Service — who were protecting Noem, law enforcement sources tell TMZ. Padilla appears to resist when asked to put his hands behind his back — prompting officers to force him nearly face-down to the ground while they handcuff him.

The Department of Homeland Security posted a scathing statement about the situation, accusing him of choosing “disrespectful political theatre” to interrupt a live press conference.

That statement says Padilla did not identify himself or comply with officers’ demands, and they therefore “acted appropriately.”

Padilla’s office released a statement saying the senator “was in the federal building to receive a briefing with [U.S. Air Force] General Guillot and was listening to Secretary Noem’s press conference. He tried to ask the Secretary a question, and was forcibly removed by federal agents, forced to the ground and handcuffed. He is not currently detained, and we are working to get additional information.”
