An energetic crowd, plus an unexpected interruption, marked Democratic presidential candidate Bernie Sanders’ visit to Amherst, Massachusetts on Saturday.

Sanders outlined his priorities to about 1,900 people in a Umass auditorium. Another 1,500 watched on a video screen outside. As Sanders spoke about income inequality, he was interrupted by a man wearing a Donald Trump t-shirt.

“Here’s a Trump supporter, worried about Mr. Trump’s money,” Sanders said. The man was escorted out as the crowd booed, and Sanders took control again.

“I say to Mr. Trump and his supporters that the billionaires of this country will not continue to own this nation,” Sanders said to loud cheers.

The Vermont Senator later headed to a second rally in Worcester. Meanwhile, Donald Trump visits the Bay State on Monday.
