Former “CBS Evening News” anchor Jeff Glor — who was replaced by Norah O’Donnell — was fired from the Tiffany Network as part of Tuesday’s sweeping layoffs at parent company Paramount Global.

Glor, who held the anchor chair once held by Walter Cronkite and Dan Rather from 2017 to 2019, had been relegated to weekend duty after his ouster as co-anchor of “CBS Saturday Morning” and as a special correspondent for the CBS News Post.

A source familiar with the situation speculated that Glor’s salary was “too high” and that he largely kept to himself, choosing not to engage in “office politics” or go out on a limb since being transferred to weekend duty.

CBS and a representative for Glor did not comment. Puck posted the news of Glor’s departure on X.

Glor was ousted from the “CBS Evening News” as part of a fierce internal campaign by O’Donnell, The Post previously reported.

O’Donnell, who co-hosted the network’s morning show with Gayle King, convinced then-CBS News President Susan Zirinsky to give her the Glor job and move the limited-ratings show from New York to Washington, D.C., said it from sources.

The decision proved costly for CBS.

Not only did the station spend a lot of money to move the show, but the third-place show’s ratings didn’t change as a result.

During O’Donnell’s five years at the helm, ratings have fallen by about 25%, leaving the newscast well behind rivals ABC and NBC.

CBS News leaders announced this summer that O’Donnell would vacate the anchor chair after November’s presidential election.

To save costs, the network will also bring the show back to New York and revamp it under the leadership of CBS News journalist John Dickerson and WCBS anchor Maurice DuBois.

The changes come as CBS parent company Paramount is in the process of laying off 2,000 employees to cut $500 million from its budget ahead of its planned merger with Skydance Media, which is expected to close next year.

On Tuesday, Paramount initiated the second phase of layoffs that began in August.

The company said 90% of layoffs would be completed and the final 10% would occur at a later date.

Sources told the Post that the cuts were expected to be completed by the end of 2024, noting that CBS News’ Washington, D.C. bureau would likely be affected after the election.
