Trump claims without evidence that celebrities were paid to endorse Harris

President urges major investigation' of Beyonce, Oprah, Bruce Springsteen and others in late-night social media rant

Donald Trump laced into a few celebrities who endorsed Kamala Harris in late night and early morning screeds on Monday, saying he would investigate them to see if they were paid for the endorsements - repeating a common refrain on the right about the star-studded list of Harris supporters.

How much did Kamala Harris pay Bruce Springsteen for his poor performance during her campaign for president?" Trump posted in all caps on Truth Social at 1.34am Monday. Why did he accept that money if he is such a fan of hers? Isn't that a major and illegal campaign contribution? ...And how much went to Oprah, and Bono???"
