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

Bad Bunny threw his support behind Vice President Kamala Harris on Sunday by sharing a video of the Democratic presidential nominee shortly after a comedian at Donald Trump's Madison Square Garden rally made crude jokes about Latinos and called Puerto Rico a "floating island of garbage," angering artists and some Hispanic Republicans.

Bad Bunny, whose official name is Benito Antonio Martínez Ocasio, is one of the most famous artists of the moment. His backing could be a boost for the Harris campaign as it tries to bolster its support with Latino voters, among whom Trump has been working to gain ground.

The video Bad Bunny shared with his 45 million Instagram followers shows Harris saying "there's so much at stake in this election for Puerto Rican voters and for Puerto Rico." A representative of the artist confirmed that Bad Bunny is supporting Harris.

Vice President Kamala Harris appeared on Monday's episode of NFL player and TV host Shannon Sharpe's "Club Shay Shay" podcast to criticize former President Donald Trump as "full time focused on himself."

Trump, Harris said, is "somebody who has never been understanding of the issues that affect the community about disparities," accusing the former president of having "denied rent to Black families" when he was a landlord and noting his "full page ad in the New York Times against the Central Park Five."

"Don't think you're in Donald Trump's club," Harris continued. "He's not gonna be thinking about you."

"He'll spend full time talking about his grievances, about what everyone has done to him," Harris said of Trump's rallies. "He'll talk about himself, but he does not talk about the American people."

Almost 42 million Americans have cast a vote through early voting methods, as of Sunday afternoon, according to data from the University of Florida's Election Lab.

The about 41.9 million recorded mail and early in-person votes were evenly split with about 21 million mail ballots returned nationally and about the same cast at in-person early voting polling sites across the country, the data showed.

Early voting options are now open to voters in 50 states and the District of Columbia. Many early voting periods will last until the weekend before Election Day.

Former President Barack Obama appeared on a Zoom call with the group Win With Black Men on Sunday.

The group -- which raised $1.3 million in four hours for the grassroots platform on behalf of the Harris campaign -- warned of the dangers of being apathetic as Black men and the importance of staying engaged in politics.

"Donald Trump has shown utter disrespect and disregard for our communities, and for Black men specifically, throughout his career," Obama said.

Drawing from former First Lady Michelle Obama's Saturday Harris campaign speech, Obama expressed disbelief that the race is neck and neck.

"As my wife said yesterday, some of you I'm sure, caught her speech in Kalamazoo. It shouldn't be this close, because the candidates are not comparable. You have on the one hand, Donald Trump, somebody who, as president of the United States, showed contempt for huge sections of the country, who did not show the capacity to move legislation that actually helped ordinary people," Obama said.

"And on the other side, you've got Kamala Harris, who at every stage, has shown herself to be a champion of ordinary people, who works to provide a voice for folks who need it," Obama continued.

"Who has displayed consistent excellence at every level, from being a district attorney to being an attorney general of California to being a U.S. senator and now to being vice president, she is as qualified as any presidential nominee that we've ever seen, and her message is directly focused on the challenges that we face as black men, and that our communities face and that America faces," Obama said of Harris.

Obama also debunked the notion that Trump is worth voting for because of the stimulus checks sent out during the pandemic.

"Well, during the pandemic, Trump sent us a check. You know what? First of all, it was Congress and Democrats and Republicans who sent you a check, just like Joe Biden, working with Congress, sent you a check during the pandemic emergency relief, just like I sent emergency relief to people during the Great Recession when I first came into office -- the difference is that Joe Biden and I did not put our names on the check," Obama said.

"So do not think that somehow, because you got a check from Donald Trump, quote, unquote, during the pandemic, that somehow that's something special that he did, and that justifies you giving him his vote," Obama said.
