Kid Rock has been a vocal supporter of the president for years, even making appearances in the White House during Trump's first few years as president.
The musician last month even headlined a Make America Great Again! campaign event in his homestate of Michigan, in Macomb County, in fact - a county that notoriously flipped last presidential election and helped catapult Trump's win to the White House. Donald Trump Jr. also attended that rally.
Thursday's debate was the final one between the two presidential candidates and is the second in-person debate to take place this election cycle.

It featured two large plexiglass shields placed in front of the candidates’ lecterns to reduce the risk of coronavirus transmission on stage. The candidates will appear on stage exactly 12.25 feet apart, and all audience members were required to wear masks.
Kid Rock and Daly were seen photographed sitting in their seats sans face masks before the debate began. They were reportedly approached by an employee and handed fresh masks to wear.
