"Clown", "Liar", "just shush for a minute" and "keep yapping" were the insults that will forever be the highlight of the first Trump-Biden US presidential debate 2020 with Fox News anchor and moderator Chris Wallace coming in for serious flak based on how he allowed American President Donald Trump to aggressively interrupt his Democratic challenger Joe Biden throughout the first US presidential debate in Cleveland, Ohio.

Trump snarled, grimaced and wagged his fingers at Biden repeatedly throughout the 90-minute debate. At one point, he said: "I'll tell you Joe, you could never have done the job that we did. You don't have it in your blood."
