Barack Obama sang Eminem's rap hit "Lose Yourself" to a crowd in Detroit during a campaign rally for Kamala Harris.

He was preceded by Eminem himself, who told the crowd in his hometown: "It's important to use your voice, I'm encouraging everyone to get out and vote, please... I think nobody wants an America where people are worried about the punishment of what people are going to do if you make your opinion known. I think Vice President Harris supports a future for this country where these freedoms and many more are protected and upheld."

Obama then opened his speech by saying, “I have to say, I’ve done a lot of rallies, so I don’t usually get nervous, but I was kind of nervous following Eminem,” before launching into the opening lines of “Lose Yourself”: “I notice my palms are sweaty, my knees are weak, my arms are heavy, my vomit is already in my sweater, my mom’s spaghetti. I’m nervous, but on the surface I look calm and ready to drop bombs, but I keep forgetting,” and the crowd erupted in applause.

He joked that he thought Eminem would perform and he would be a guest star, adding: "I want an Eminem dick."

The former president is a known music fan, sharing his favorite songs twice a year on his official social media posts. The summer 2024 selections included songs from contemporary pop names like Beyoncé, Tyla and Rema alongside older songs from Nick Drake, the Supremes and cosmic jazz musician Pharoah Sanders.

Obama continued to rebuke Donald Trump in his speech, recalling how Trump expressed doubts about the results of the 2020 election.

“Because Donald Trump was willing to spread lies about voter fraud in Michigan, protesters came down, smashed windows, yelling, ‘Let us in. Stop the counting.’ Poll workers inside were scared… all because Donald Trump couldn’t accept defeat… there is absolutely no evidence that this man thinks about anyone but himself.”

He questioned Trump's mental fitness for the role of president, saying: "You would be worried if Grandpa behaved like this. But this is coming from someone who wants unchecked power."

He also referenced Trump earlier this week, where he worked in a McDonald's kitchen and counter that was closed to the public. Harris, he said, "worked at McDonald's when she was in college to pay her bills. She didn't claim to be working at McDonald's when it closed."

Tim Walz, also speaking at the rally, criticized the stunt as “cosplaying … Fake orders for fake customers.” He also called for free speech, saying Trump “was talking about sending the military against people who don’t support him. He’s calling names.”
