In the lead-up to Thursday's CNN Presidential Debate, former President Donald Trump has called for both himself and President Joe Biden to undergo drug tests. Trump alleges that Biden may use performance-enhancing drugs, a shift from his usual critiques regarding Biden's age. Representative Ronny Jackson has sent a letter to President Biden and the Physician to the President, Dr. Kevin O’Connor, demanding Biden take a clinically validated drug test immediately before and after the debate. Trump has agreed to take the test himself and has challenged Biden to do the same. The debate, moderated by Jake Tapper, will address key issues such as illegal immigration and Ukraine. The debate preparations have been marked by heightened tensions, with Trump supporters claiming the event is unfairly rigged against him.
