“If you touch me again, I’ll drop your ass,” Rep. Stephen Knight (R-CA) told a man whom he called “Mike.” The video was posted by We the People Rising, a group that, according to its website, is a grassroots organization that opposes illegal immigration.

In the video, Mike and his fellow protesters repeatedly accuse Knight of having voted for President Obama’s “amnesty.” Knight claimed he “never voted for amnesty” — a claim the protesters scoffed at.

“Oh, come on!” one said. “We’re gonna vote you out in two years when your term’s over!” another said. Protesters were holding signs that read, “Stop Illegal Immigration” and “Secure The Border.”
