Eminem endorsed Vice President Kamala Harris at a rally with Obama at a rally in Detroit, Eminem’s hometown.

“As most of you know, the city of Detroit and the whole state of Michigan mean a lot to me. And going into this election, the spotlight is on us more than ever,” Eminem, a longtime critic of former President Donald Trump, told the crowd. “And I think it’s important to use your voice. So I’m encouraging everybody to get out and vote.”

Obama walked out to Eminem’s “Lose Yourself,” saying “my palms are sweaty,” a line from the song. He then rapped several lines from “Lose Yourself.” 

Trump’s former chief of staff John Kelly in a pair of interviews released Tuesday voiced serious concerns about Trump’s ability to lead, saying he fits “the general definition of fascist,” had privately praised Adolf Hitler and his generals — and would govern like a dictator if he returns to the White House.

The Trump campaign denied Kelly’s accounts in both stories.

Democratic vice-presidential nominee Tim Walz on Tuesday night responded to a report in The Atlantic that Trump had praised Hitler’s generals, saying it made him “sick as hell.”

“The guardrails are gone,” Walz said. ” Trump is descending into this madness. A former president of the United States and the president of the United States says he wants generals like Adolf Hitler had. Think about it. And he already has the Supreme Court in his pocket. They’ve effectively given him full immunity.”

Vice President Kamala Harris, asked by NBC News’ Hallie Jackson if her team has a plan, should Trump declare victory on election night before all the votes are counted, said she’ll be ready.

“We’ve got two weeks to go, and I’m very much grounded in the present, in terms of the task at hand, and we will deal with election night and the days after, as they come, and we have the resources and the expertise and the focus on that, as well,” she told Jackson in an interview that aired Tuesday on “NBC Nightly News”
