"Sports has never been something that divides people, it's always been something that brings something together", he said.
"He doesn't understand the power that he has for being the leader of this handsome country", James said. Lemon's chief offense was apparently making James look smart, which Trump said "wasn't easy to do".
James - who had been on CNN to discuss the new school he opened last week in his hometown of Akron, Ohio - had yet to respond to Trump's dig early Saturday, but he has clapped back at the president in the past. Shortly before midnight, he made his thoughts known on what he thought of the LeBron-Lemon conversation. "I like Mike!" the tweet read.
Donald Trump is travelling to OH on Saturday for a campaign rally.
The Governor is clearly referring to LeBron's recently-opened I Promise School in Akron, Ohio which is set out to provide free, quality education - among other things - to hundreds of underprivileged kids.
"If we look at some of the greatest leaders of our time, you look at, you know, Muhammad Ali, you look at Dr. Martin Luther King, and all the adversity they went through", he told Lemon.
Trump as been vocal in the NFL national anthem debate, suggesting NFL players should be "fired" for "disrespecting the flag".
LeBron has yet to speak out about Donald's latest slamming tweet but it will be interesting to see what he says, if anything!
James also chose Los Angeles in part because it represents the next chapter in his life.
Trump has repeatedly been questioned about his views on race, from deeming many Mexican immigrants "rapists" during his campaign kickoff speech for the Republican presidential nomination to placing blame on "both sides" for the violent clash between white supremacists and counterprotesters in Charlottesville, Virginia, a year ago.
