WATCH: CNN’s Jake Tapper Teaches Biden How to Cough Properly in Awkward Interview Moment

CNN anchor Jake Tapper took former Vice President Joe Biden to school on Tuesday, showing the 2020 Democratic front-runner how to properly cough during an on-air interview.

Biden was discussing the latest on combating the pandemic from his home when it was interrupted by a cough.

“Excuse me,” Biden said after he coughed into his hand.

“You know, you’re supposed to cough into your elbow,” Tapper told the former vice president as he himself demonstrated with his elbow. “I learned that, actually, covering your White House.”

“Actually, that’s true,” Biden conceded. “But fortunately, I’m alone in my home, but that’s OK. I agree you’re right.” (Read more from “WATCH: CNN’s Jake Tapper Teaches Biden How to Cough Properly in Awkward Interview Moment” HERE)
