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.”

During brief remarks, before introducing Obama, the rapper said people “shouldn’t be afraid to express their opinions” and voiced his support for Harris.
