Although James has always been a Trump critic, calling the president "U bum" in a 2017 tweet, the Friday night tweet was Trump's first attack on the player, who just opened up a school for underprivileged children in his hometown of Akron.
James's last message was about his newly completed I Promise School in Akron, a public and nonprofit partnership created to help underserved kids in his OH hometown.
Trump resorted to childish name-calling in a Friday evening tweet in which he slammed the intelligence of both James and CNN anchor Don Lemon.
Trump called Lemon "the dumbest man on television", then implied LeBron is dumb.
Lemon fired back: "Who's the real dummy?"
Trump is traveling to OH on Saturday for a campaign rally.
"I like Mike!" he wrote.
Northern California wildfire raging into its fourth day
The Carr Fire destroyed almost all of Keswick, a hamlet just west of Redding, which is about 250 miles north of San Francisco. Wildfires around the state have forced roughly 50,000 people from their homes, said Lynne Tolmachoff, a Cal Fire spokeswoman.
But Lemon and James, the three-time National Basketball Association champion and four-time league MVP, also touched on a few other subjects that led to Pres. Donald Trump, who must have been watching CNN Friday night and the Lemon-James interview specifically, tweeting out decidedly un-presidential attack on Lemon and James' intelligence. CNN is also one of Mr. Trump's favorite foes.
The tweet was referring to an unverified story that Trump was recently angry after discovering that his wife's TV on Air Force One was set to CNN. The basketball star recently opened an I Promise School for low income and at-risk kids in OH, inspired by his own upbringing.
Attacking Mr Trump, James later tweeted: "U bum @StephenCurry30 already said he ain't going!"

James admitted he was happy to his public profile to battle the president.
Lemon - who, along with his network, has been the subject of repeated attacks from Trump - was among those who came to the defense of the former Cleveland Cavaliers star, who is now with the Los Angeles Lakers.
Flashing the trademark smile that has routinely graced magazine covers and commercial shoots since he was a junior in high school, James laughed at learning how much earlier his youthful "white friends" ate dinner and went to bed, and noted his surprise at seeing food stored in a pantry. "For kids, in general, all they want to know is that someone cares".
