US President Joe Biden is still under fire for his June 27 performance in a debate against Republican competitor Donald Trump. Since the US President stammered and muttered during the discussion with Trump, there has been concerns about his mental clarity. Joe Biden doesn’t need a cognitive test, according to White House physician Kevin O’Connor. Biden stated that there were “no indications of any serious condition” and that exhaustion was the sole problem while speaking to the ABC about his subpar debate performance.
