Milan, 19 May (LaPresse) – Donald Trump has lashed out against Bruce Springsteen, Beyoncé, Oprah Winfrey and Bono, claiming that they received illegal payments to support Kamala Harris's election campaign and announcing that he will call for an investigation into the matter. 'How much did Kamala Harris pay Bruce Springsteen for his poor performance during her presidential campaign? Why did he accept this money if he is such a big fan of hers? Isn't this an illegal and huge campaign contribution? And Beyoncé? … And how much did Oprah and Bono get? I will demand a thorough investigation into this matter,‘ the US president wrote in a post on his social media platform Truth. ’Candidates are not allowed to pay for endorsements, which Kamala did under the guise of paying for entertainment,‘ Trump alleged. ’Furthermore, this was a very expensive and desperate effort to artificially boost her low numbers. It's not legal!‘ he continued, stating that ’for these unpatriotic “entertainers,” this was just a corrupt and illegal way to take advantage of a broken system."
