2024 election updates: Trump and Harris bring their campaigns to the battleground state of Wisconsin

Puerto Rican reggaeton singer Nicky Jam has withdrawn his endorsement of Donald Trump in the 2024 presidential election a month after appearing at a rally for the candidate.

Tony Hinchcliffe, a comic who called Puerto Rico "garbage" before a packed Trump rally in New York appears to be the catalyst.

"The reason why I supported Donald Trump was because I thought he was the best for the economy in the United States, where many Latinos live, many of us Latinos live, myself included, many immigrants who are suffering because of the economy and him, being a businessman, I thought it was the best move," Jam said in Spanish, in a video statement posted to his official Instagram page.

"Never in my life did I think that a month later a comedian was going to come to criticize my country and speak badly of my country and therefore, I renounce any support for Donald Trump, and I sidestep any political situation. Respect Puerto Rico, Nicky Jam."

A representative for Jam confirmed on Thursday that the singer had withdrawn his endorsement.

Harris and her allies in battleground Michigan are launching a new turnout campaign to assertively shore up support among Arab Americans, sending out mailers using Trump's own words about reimplementing a Muslim ban.

"Just last month, Donald Trump said he would ban Muslims from traveling here, and also ban refugees from Gaza," one of the mailers obtained by ABC News reads. Further down, the mailer says the former president "is no friend to Arab Americans," with one of their examples being his comment that he would let Israel "finish the job" in Gaza.

Another is a full-page black-and-white photo of Trump with "FINISH THE JOB" written above him. "That's what Trump said he would let Israel do in Gaza." The mailers, which come on the heels of a six-figure digital ad push, also points to the Arab American group Emgage Action's endorsement of Harris. (A number of other Arab leaders have backed Harris.)

Michigan, a state that was narrowly won in 2016 and 2020, is a target of both Harris and Trump's campaigns and has the largest Arab-American population among the states that will help decide the election. And Trump is making a play for them, too. Over the weekend, in Novi, Michigan, Trump invited Muslim leaders to the stage who are backing him, including Hamtramck, Michigan, Mayor Amer Ghalib.

Pro-Palestinian protestors who take issue with the U.S. response have demonstrated at Harris' rallies, including on Tuesday night as she delivered her "closing argument" speech outside the White House and Wednesday at a rally in Harrisburg, Pennsylvania.

"Look, I'll repeat: We are fighting for our democracy. We love our democracy. It can be complicated at times, but it is the best system in the world," Harris said after several interruptions from demonstrators.

Harris, at a news conference on Thursday, swiped at House Speaker Mike Johnson's comments about making "massive reform" to gut the Affordable Care Act.

"I've been saying throughout this campaign, be very clear that among the stakes in this election are whether we continue with the Affordable Care Act or not," she said. "It has been a part of Donald Trump's agenda for a very long time. He has made dozens of attempts to get rid of the Affordable Care Act, and now we have further validation of that agenda from his supporter, the speaker of the House."

"What that would mean for the American people is that pharma -- that insurance companies could go back to a time when they would deny you coverage for health insurance based on pre-existing conditions, pre-existing conditions such as being a survivor of breast cancer, asthma, diabetes," she added.

The Trump campaign is trying to distance itself from Johnson's comments, telling The New York Times they are "not President Trump's policy position."

Trump is also seeking to separate himself from the remarks, despite saying numerous times this campaign that he would replace the ACA without offering a clear alternative.

Trump called Harris a "liar" and said her comments were a "desperate" attempt.

Harris, while speaking to reports before departing Wisconsin, said she found Trump's comments about women "offensive to everybody" and that, in contrast, her campaign is about unifying people.

Harris, speaking with reporters before departing Wisconsin, continued to slam Trump for his comments that he will protect women "whether they like it or not."

"You've been following me and you will see that in the tens of thousands of people who attend our rallies ... there are men, women, young people, people of every race, every background," she said.

Harris said her campaign is "about bringing people together, people of very different and diverse backgrounds, around a common theme that is about love of country, defending the Constitution of the United States, investing in our future and rejecting the notion that we are divided."
