Controversy surrounds Trump's UIC rally Friday

CHICAGO (FOX 32 News) - Donald Trump is holding a rally in Chicago Friday.

Trump is coming to The Pavilion on the Near West Side's University of Illinois Chicago campus. It can hold more than 9,000.

His political foes plan for a big crowd outside, too, with rhetoric already red hot.

“You've seen the racist things he's said. You've seen what he - he knows they're not true!” said Rep. Luis Gutierrez.

“Any effort to paint Donald Trump as a racist is beyond despicable. It is completely false. It is ridiculous,” said Trump supporter Douglas Ibendahl.

Ibendahl attended Trump's standing room only rally in Springfield a few months ago. He's looking forward to the Friday night rally at the University of Illinois Chicago Pavilion, where he may encounter a group of Hispanic activists – all Democrats - who promised protestors would demonstrate outside Trump's rally.

“We need to wake up, because we are in danger,” another Trump supporter said.

But a more immediate danger to Trump’s presidential campaign comes from some of his fellow billionaires. They and other wealthy donors are bankrolling a new round of attack ads and some are intended to convince conservatives that Trump is not really one of them.
