Crowd erupts as Vance smacks down protester waving Mexican flag: 'Get your a-- over there'

Vice President JD Vance blasted a heckler waving foreign flags and yelling at him from the GOP convention floor during his primetime keynote address Thursday night.

The rabble-rouser emerged from the crowd waving Mexican and Palestinian flags, catching Vance's eye as he delivered his rallying cry to thousands of GOP voters at the American Airlines Center in Dallas. The incident wasn't captured by the convention's official television feed, but Vance described it for viewers at home.

"What the people at home missed is that we just had a protester interrupting us and waving the Mexican flag.," he said. "Well, my friend, if you love Mexico so much, get your a– over there. I'll buy you the plane ticket."

JD VANCE TO INVOKE CHARLIE KIRK, FAMILY BIRTHRIGHT IN FIERY MIDTERM KEYNOTE SPEECH THRASHING DEMS

The crowd erupted into chants of "USA! USA! USA!" as the troublemaker was escorted out of the event.

Vance delivered a deeply nationalistic keynote focused on America First principles.

"I believe the Founders built this nation on a promise that echoes our Creator: That every American child is born an heir, born with a birthright," said Vance. "Born with the right to inherit the blessings of this country. Not because of who their parents are. Not because of what they look like or where they come from. But because they are Americans."

Throughout his speech, event attendees interrupted with a chorus of "JD! JD! JD!" chants, and the roared as finished and departed the stage.
