Eminem made brief remarks at a Kamala Harris rally in Detroit on Tuesday evening, talking about the fear of retribution people have for expressing their opinion, and his belief that Harris would protect freedom of speech as President.

Obama himself came out to Eminem ‘s “Lose Yourself,” going so far as to rap along the first few bars of the song. “I was feeling some kind of way following Eminem,” he said, reciting the opening verse from the track. “I thought Eminem was going to be performing, I was going to jump out. Love me some Eminem.”
