Lemon pointed out James's recent decision to open a school in Ohio for at-risk third- and fourth-graders as evidence that the NBA star was no "dummy" after Trump wrote Friday that Lemon had managed to make James look intelligent, which he said wasn't "easy to do."

"Who’s the real dummy? A man who puts kids in classrooms or one who puts kids in cages?" Lemon tweeted Saturday, including the hashtag "Be Best" used by first lady Melania Trump Melania TrumpThe Hill's Campaign Report: Trump faces backlash after not committing to peaceful transition of power FBI director casts doubt on concerns over mail-in voting fraud Trump: 'We could hardly hear' boos, chanting at Supreme Court MORE on her anti-bullying campaign.

Trump insulted James over Twitter and appeared to reference former NBA star Michael Jordan in a tweet late Friday after James appeared on Lemon's show earlier in the week and denounced what he said was the president's use of sports to divide the country.

“Lebron James was just interviewed by the dumbest man on television, Don Lemon. He made Lebron look smart, which isn’t easy to do,” Trump tweeted. "I like Mike!"

In the CNN interview, which centered on James's decision to open a public school in his hometown of Akron, Ohio, James also appeared to indicate that he was open to the possibility of running for president, a question that has provoked the president to attack other sports stars, actors and political figures in the past.

"If someone tried to recruit a James to run for president, they said, 'Listen, they've got no one, if you don't run, Trump's going to win,' would you run?" Lemon asked the former Cleveland Cavaliers star who recently signed with the Los Angeles Lakers.

"Well, in that case, I may," James responded. “If they have no one? I believe there’s some people out there. I hope. Let’s see, first.”

CNN anchors have frequently criticized the the president and his administration over Trump's labeling of the news network and its journalists as "fake news."

Lemon himself has been a particular target of Trump in the past, who has called him the "dumbest man on television."
