On Monday (Jan. 20), Donald Trump was sworn in as the 47th president of the United States and celebrated the feat with multiple balls taking place across Washington, D.C. Nelly was a special performer at the Liberty Inaugural Ball where he gave the crowd a medley of songs including "Hot in Herre," "E.I.," "Country Grammar," "Dilemma" and more.

Nelly defended his decision to perform at Donald Trump’s inauguration Monday while speaking to HuffPost’s Phillip Lewis. “He’s the president. He won. This isn’t a campaign,” he said. “This isn’t an RNC. I’m not out on the political campaign. I didn’t get none of that 1.5. You see what I’m saying?”
