Trouble On The 'CNN This Morning' Set As Lemon Screams

Poppy, Don and Kaitlan

According to two sources with knowledge of the situation, the 56-year-old Lemon approached 30-year-old Collins following the show’s Thursday Dec. 8 broadcast — and unloaded on her in front of staffers as he accused her of “interrupting” him on air, reports The NY Post.

“Don screamed at Kaitlan, who was visibly upset and ran out of the studio,” one source with knowledge of the skrimish said.

News of the explosive incident made its way up to CNN CEO Chris Licht, who is said to have been appalled by Lemon’s behavior, according to a source. A second source said a producer talked to Lemon at the behest of Licht and told the anchor to take the next day off to “cool off.”

The following night, the three co-hosts were slated to get drinks and arrive together at a White House Christmas party for the press, a source said. But the pre-party gathering never happened after the emotional day and they trickled-in to the bash separately, an insider with knowledge said. After the party, Lemon had a late-night dinner with his agent, Jay Sures, according to sources.

The situation was especially awkward because Collins — a rising star who had most recently served as CNN’s youngest chief White House correspondent — is also represented by the powerful and well-connected Sures. While he dined with Lemon, Collins met up with the show’s other co-anchor Poppy Harlow, the sources said.

“At this point, Kaitlan wants to be on set with Don as little as possible,” a source with knowledge of the situation added. “It’s messy.”

Neither Lemon nor Collins responded to requests for comment.
