WATCH: Biden calls Trump 'the loser' for allegedly insulting dead soldiers | CNN Presidential Debate

President Joe Biden and former President Donald Trump traded attacks over who has been the better supporter of veterans, as well as a report that the former president had called soldiers buried at a World War I cemetery “suckers” and “losers.”

Biden criticized Trump for his reported remarks and raised his own son Beau, who died of cancer after serving in Iraq.

“My son was not a loser. He was not a sucker. You're the sucker. You're the loser,” Biden said.

Trump called the quote “made up” by a “third-rate magazine” and that others have supported his claim that he did not make the remark.

The June 27 CNN Presidential Debate is the first time Biden and former Trump are facing off this election season. It is also the first time they have debated since 2020. This matchup will also be the first debate between a sitting and former president.
