In a tweet shared on Saturday morning, CNN’s Don Lemon shot back at President Donald Trump calling him “the dumbest man on television.”

Lemon’s response comes on the heels of President Trump’s early Saturday morning post via social media insulting Lemon and NBA superstar Lebron James following their interview about the opening of James’ I Promise school in Akron, Ohio.

The tweets have garnered a strong reaction from several people on social media. Among those who have commented are CNN’s Anna Navarro and Angela Rye and legendary journalist Dan Rather.

These tweets aren’t the first time President Trump has insulted Don Lemon. Over the years, he has called Lemon the dumbest man on television. This is the first time he has insulted James. In the past, James has made his feelings known in the past about Trump. James has not posted a response to Trump’s latest insult.
