The executive producer of “CBS Mornings” is headed for the exit – one day after the struggling show’s star anchor Gayle King inked a new deal to stay at the network. 

The upheaval comes as CBS News editor in chief Bari Weiss is in the throes of revamping the third-place broadcasting hub – and key to that task is turning around its struggling morning show, sources close to the situation told The Post.

Shawna Thomas, who has run “CBS Mornings” since 2021, had been on the hot seat over polarizing programming – including a segment last year that featured “Bob the Drag Queen” – which critics claim has alienated traditional morning show viewers, The Post previously reported.

Sources said Thomas’s departure is a bitter pill for King, who re-upped her contract to remain at “CBS Mornings” this week – even as chatter circulates that King’s pay package is getting cut in half.

Thomas, seen by staffers as King’s right hand, had often pushed back on suggestions from top brass as they searched for ways to overhaul the ratings-challenged show, sources said. 

“She’s been a roadblock to making changes,” said a source with knowledge, noting that the problem grew knottier as King “empowered” Thomas to set an “agenda” that has translated to viewership losses.

At the same time, a source noted that under Weiss and CBS News president Tom Cibrowski, who has been tasked with revamping “CBS Mornings,” Thomas has seemed, at times, “resigned” to her eventual fate.

“They put her out of her misery,” the source added. 

CBS News didn’t respond to a request for comment.

Under Thomas, “CBS Mornings” — once regarded as a cash cow for the beleaguered news division — has seen its ratings plummet below 1.8 million daily viewers in recent months. 

Critics have pointed to Thomas’ programming, which has focused on diversity, equity and inclusion versus covering topics that appealed to middle America like small finance issues and health, a source with knowledge told The Post at the time. 

One insider cited a March 26 interview with “RuPaul’s Drag Race” winner Bob the Drag Queen, who was publicizing his first novel, “Harriet Tubman: Live in Concert.”

The “CBS Mornings” website described the book as a “gender-bending story where the historic icon appears in modern-day America to tell her story through a hip-hop album,” as previously reported by The Post. 

At the time, then-CBS News CEO Wendy McMahon hired Cibrowski, a former “GMA” senior producer, to help amp up the ratings and work with Thomas. Cibrowski was named CBS News boss after McMahon’s exit in May.

Two sources told The Post that Thomas was initially supportive of his ideas to tweak programming, but that Cibrowski soon hit similar roadblocks. Recently, a source close to the network said Cibrowski and Thomas had appeared to establish a good working relationship.

Thomas informed staffers of her exit on Thursday via a note that she sent to colleagues, Variety first reported.

“For five years, I’ve tried to make this show something you all want to watch. Want to be a part of. Want to learn from,” Thomas wrote in the memo. “I’ve taken that responsibility of trying to inform, educate, entertain and make people care about the world around them very seriously and I know the people here do, too.”

Cibrowski is expected to add a new anchor to co-host the show alongside King and Nate Burleson. 

The new anchor will fill the spot left open by Tony Dokoupil, who was promoted to anchor of “CBS Evening News.”

The network is expected to cycle through guest hosts to fill the slot, including Josh Elliott, who worked with Cibrowski when he was an anchor at “GMA” from 2011 to 2014. Elliott has been out of an anchoring gig for nearly 10 years, since he was let go from CBS News in 2017.

Weiss, who co-founded centrist website The Free Press, was named CBS News editor in chief in October by David Ellison, the CEO of CBS-parent Paramount Skydance, to bring balance and “bipartisan dialogue” to the network.
