Washington: Democratic presidential nominee Joe Biden has said that he shouldn't have called US President Donald Trump a clown during the first debate between the two rivals on September 29.
"I should have said this was a clownish undertaking instead of calling him a clown," The Hill news website quoted Biden as saying in an NBC News town hall on Monday.
The former Vice President said it was hard to engage respectfully with Trump during the 90-minute debate, which took a chaotic turn with insults such as "liar", "just shush for a minute" and "keep yapping".
"It was just very difficult. I didn't want to further demean the process of the debate by getting in a shouting match with him.
"I'll be very honest with you. I think it was embarrassing for the nation to see the president hectoring like he did," Biden added.
