Donald Trump today called on his supporters to boycott Bruce Springsteen concerts, in another heated clash with the rock star. "Bruce Springsteen, this bad and very boring singer, who looks like a dried prune and clearly bears the marks of a failed plastic surgery, has long suffered from a terrible and incurable anti-Trump disorder syndrome," wrote the American president in a message published on his Truth Social platform. "Trump supporters should boycott his terrible and overpriced concerts," continued the American president, while also praising his own political career. At 76 years old, the singer of "Born in the USA" began a tour in Minneapolis, Minnesota, the epicenter of the U.S. government's immigration enforcement actions earlier this year and a hub of opposition to the Republican president. During the "No Kings" protests, the American artist harshly attacked Donald Trump, calling him "corrupt, incompetent, racist, irresponsible, and a traitor." He then performed his song "Streets of Minneapolis" for the crowd, which he wrote in memory of Renee Goode and Alex Pretty, who were fatally shot by federal agents during immigration raids. His American tour "Land of Hope and Dreams" is expected to visit about 20 American cities by May 27.
