Days after Bruce Springsteen slammed Donald Trump at a European concert, the president now says he's calling for a "major investigation" into the Boss and other celebrities' endorsements of Kamala Harris,

Bruce Springsteen ‘s criticisms of Donald Trump last week appear to have triggered the president even further, as he is now calling for an investigation of the superstar singer’s endorsement of Kamala Harris, as well as other entertainers.

The remarks came mere hours after Trump took a similar swipe at Bruce Springsteen and claimed that he was going to call for a "major investigation" into the matter. He had also launched a similar tirade against popstar Taylor Swift last week.
