Kid Rock, known offstage as Robert James Richie, was speaking during an interview with far-right Fox News host Tucker Carlson on Monday night.
In his interview with Mr Carlson, the rock star said he still plays golf with Mr Trump.
Pro-Trump musician Kid Rock has claimed there are “a ton” of prominent people in Hollywood who are “closeted” supporters of the former president.
Asked by Mr Carlson whether there were others in showbiz who shared his views, Mr Ritchie said that during the 2020 election Trump aides would often privately name “Hollywood people” who were “in the closet”.
