Jon Bon Jovi hit the campaign trail in support of Democratic presidential candidate Hillary Clinton on Wednesday (June 1), first in Newark, NJ and later that evening at a fund-raising event in Boston.

Bon Jovi and New Jersey Senator Cory Booker joined Clinton at a campaign event at Rutgers' Newark campus, where he introduced the former First Lady, U.S. Senator and Secretary of State.

"I just like to refer to her as Mrs. C," Bon Jovi said. "I hope that soon we will be calling her Madame President."

After cheers from the crowd, Clinton said "it doesn't get any better than this [being introduced] by these two gentleman..these two Jersey giants."

At the rally, Clinton took aim at Donald Trump and his Trump University seminars, which she called a "fraudulent scheme."

Trump responded by calling out Clinton as a "fraud" on Twitter.

Bon Jovi was additionally scheduled to appear on the same night at the Westin Boston Waterfront to raise money for the Hillary Victory Fund.

Bon Jovi, a Clinton supporter, also donated $5,400 to New Jersey Governor Chris Christie's failed bid for the Republican presidential nomination.
