A convicted felon and leftist interrupted GOP presidential frontrunner Donald Trump’s speech in Worcester, Massachusetts Wednesday and was dragged out of the arena by police.

“Trump’s a racist!” a man shouted while standing on a chair, according to a police report.

Police said he was deliberately pushing and bumping people around him.

The assailant has been identified as Peter Rondon who pleaded guilty in 2005 for attempt to blow up a Marine Recruiting Center in Worcester and was sentenced to one year in prison.

Trump was unaware Rondon is convicted bomber, but fired back at him after the disruption.

“You know, it’s amazing,” Trump said. “I mention food stamps and that guy who is seriously overweight went crazy.”

Rondon told the Worcester Telegram & Gazette that he was peacefully protesting and that he had filed a complaint with police against people who ‘tackled’ him as he protested Trump.
