Donald Trump wasn’t happy to hear that Bruce Springsteen hasn’t backed down from calling him an “unfit president” as he performs in Europe, so he went on another rant on social media overnight Sunday, demanding a “major” investigation be launched against the rock ‘n’ roll legend for singing at a Kamala Harris rally in October.

Bruce Springsteen is one of those artists who seems to be perpetually touring, and this summer, he'll be on the road with the E Street Band once again, though this tour will only be taking him to Europe.

The 'Born in the USA' singer went on an anti-Trump tirade, and Kid Rock responded. So did President Trump. Here's what to know.

Bruce Springsteen released an EP today from his “Land Of Hope And Dreams” European tour, including the scathing comments he made about President Donald Trump. Hours later, Trump posted a mock video in which he tees off and his golf ball hits Springsteen in the head.

The lifelong Democrat is poised to antagonize the commander-in-chief for the duration of his summer-long European concert tour.

"I am not scared of you. Neither are the rest of us," the musician Neil Young wrote in a recent post on his website.
