WATCH: Sen. Alex Padilla (D-CA) was forcibly removed from Homeland Security Secretary Kristi Noem's press conference in Los Angeles.

Padilla's office shared a video of the incident with NBC News. The video shows Padilla being taken into a hallway outside and pushed face forward onto the ground as officers with FBI-identifying vests told the senator to put his hands behind his back. The officers then handcuffed him.

According to a statement from Padilla's office, "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."

In a statement posted to social media, DHS said “Senator Padilla chose disrespectful political theatre and interrupted a live press conference without identifying himself or having his Senate security pin on as he lunged toward Secretary Noem.”
