CBS News Editor-In-Chief Bari Weiss’ Commentary Costs Network Interview With NYC Mayor Zohran Mamdani 

Is Bari Weiss getting in her own way? New York City mayor Zohran Mamdani reportedly backed out of an interview with Robert Costa at CBS Sunday Morning recently—all thanks to a social media post from the CBS News editor-in-chief.

In the latest issue of his new Party Animals newsletter for Vanity Fair, Aidan McLaughlin reported that the mayor, 34, was hesitant about appearing on CBS after the network’s repeated negative coverage of him, but that one post in particular served as the “nail in the coffin,” per Vulture.

Weiss, 41, shared a post on X (formerly known as Twitter) on February 28 of a video featuring CBS News contributor Masih Alinejad criticizing Mamdani’s condemnation of the United States’s attack on Iran, adding a fire emoji.

“Bari and her people have a clear ax to grind with [Mamdani],” a source told Vanity Fair. But it isn’t just the popular Democratic Socialist mayor who is shying away from CBS in light of Weiss’s tenure (she was named editor in chief in October 2025).

“It’s not just Zohran. It’s really hard now to get people to come on CBS,” said the source.

At the time of the post, social media users responded criticizing Weiss’s lack of objectivity. “This seems like a rather partisan tweet for the head of CBS News,” wrote one X user. “We all know that you’re an incompetent right-wing grifter but I thought that you’d at least be a little more subtle about it while running cbs news,” chimed in another.
