CHICAGO (CBS) -- On the same day that he attended a private fundraising luncheon in Chicago, presumptive Republican presidential nominee Donald Trump tweeted about the city's crime issues.
"Crime is out of control, and rapidly getting worse. Look what is going on in Chicago and our inner cities. Not good!" he tweeted.
Shootings and murders have spiked significantly in Chicago this year, with more than 2,000 people shot so far, and more than 340 homicides. In all of 2015, approximately 2,900 people were shot in Chicago, and there were 478 murders.
Trump is billing himself as the "Law & Order Candidate"
Trump's fundraiser in Chicago comes four months after he abruptly canceled a campaign rally at the UIC Pavilion, amid security concerns as supporters and opponents clashed before Trump arrived.
Trump reportedly held the fundraiser at his namesake hotel downtown, although he was not seen publicly.
Donors paid $10,000 to attend, $25,000 for a photo with the candidate and $100,000 to take part in a round table discussion.
On Tuesday evening, Trump was attending another fundraiser in Westfield, Ind., just north of Indianapolis, where he is to be introduced by Gov. Mike Pence, one of Trump's finalists for vice president.
Pence introduced Trump, in what appeared to be an audition for the No. 2 spot on the ticket.
Pence said Trump understands the American people like no one since President Ronald Reagan.
He told the crowd that the country cannot let Hillary Clinton get elected and called Trump "a good man" who knows "how to make America great again."
Back in Chicago, across the river just outside Trump Tower, a small group of protesters held a news conference to denounce Trump's divisive rhetoric, and to say he's not welcome in Chicago.
"Donald Trump's rhetoric, his demeanor, and his policies make him unqualified and unfit to be the president of the United States," said William McNary, co-director of Citizen Action/Illinois.
Cook County Commissioner Jesus "Chuy" Garcia said a Trump presidency would be "disastrous."
"It would be a setback for Chicago, and Chicago cannot afford to go back. Illinois cannot afford to go back," Cook County Commissioner Jesus "Chuy" Garcia said.
Trump was expected to collect more than $1 million in campaign donations at the high-priced luncheon, but he is not getting a lot of support from Republican elected officials in Illinois.
Gov. Bruce Rauner has said he won't endorse Trump, and U.S. Sen. Mark Kirk withdrew his support after Trump attacked the federal judge overseeing a suit against Trump University. Kirk has said Trump does not have the temperament needed to be president.
Neither Kirk nor Rauner will be attending the Republican National Convention next week in Cleveland.
Regional Transportation Authority chairman Kirk Dillard, a former state senator and former Republican candidate for governor, also won't attend the GOP convention, but he said he might go to Cleveland itself.
"There is a reception for the American Public Transportation Association that I may go out for, so I'll see some of the conventioneers. I haven't spoken to the latest Trump supporter, my friend Ron Gidwitz, yet about what the future of the Trump campaign is,"
Gidwitz and other former Republican candidates for governor reportedly were hosting the Trump luncheon in Chicago.
Illinois Republicans aren't skipping the convention altogether. Illinois Republican Party chairman Tim Schneider and former chairman Dan Brady will attend. So will House Republican Leader Jim Durkin.
After his fundraiser in Chicago, Trump will go to Westfield, Indiana, for a rally Tuesday evening just outside Indianapolis.
Presumptive Democratic presidential nominee Hillary Clinton will be in the Chicago area on Wednesday, for a private fundraiser in Wilmette. She'll also be in Springfield on Wednesday for a campaign rally.
