NEWARK, N.J. (CBSNewYork/AP) — Democratic presidential candidate Hillary Clinton has received an assist from New Jersey rocker Jon Bon Jovi.

The performer joined Clinton at a campaign event held Wednesday at Rutgers’ Newark campus. Also taking part was Cory Booker, one of New Jersey’s two Democratic U.S. senators.

As CBS2’s Dick Brennan reported, Clinton aimed her fire at Donald Trump and his Trump University.

“Trump U was a fraudulent scheme where Donald Trump enriched himself at the expense of hard working people,” she said, “Trump himself is a fraud.”

In a class action suit former students claimed they were tricked into buying expensive real estate investment seminars which they said yielded little results.

The Trump camp said the complaint comes from a small number of students and has labeled the federal judge in the case — Gonzalo Curiel — a hater.

“The judge has been very unfair, has not done a good job, has not been a good judge,” Trump said.

Trump continued his attacks on the media Wednesday, via twitter.

“So I raised/gave $5,600,000 for the veterans and the media makes me look bad! They do anything to belittle – totally biased,” he tweeted.

Trump Piled on after Tuesday’s attacks on reporters.

“I’m gonna continue to attack the press. I’ve watched you on television. You’re a real beauty. This guy right over here from ABC, he’s a sleaze,” Trump said.

A new Quinnipiac Poll showed Clinton with a 45 to 41 percent lead over Trump in the race for the White House.

Voters said Trump would be better at creating jobs while Clinton received high marks for responding to an international crisis.

In the meantime, Bernie Sanders was fighting to the finish line in California where he called for a national ban on fracking.

“If elected president we will not need state by state, county by county. We’re going to ban fracking in fifty states in this country,” Sanders said.

The California and New Jersey primaries are coming up next week. Clinton is hoping she can wrap up the nomination that day.
