Anchor Norah O’Donnell leaving CBS Evening News after Thursday’s broadcast

“CBS Evening News” anchor Norah O’Donnell previously announced that her departure from “CBS Evening News” would take place on Friday, Jan. 24, but her planned exit was bumped up a day, because CBS is scheduled to air the Farmers Insurance Open Friday evening, per TV listings.

When is CBS Evening News on tonight?

“CBS Evening News” airs at 6:30 p.m. on CBS and at 10 p.m. on the CBS News app.

Why is Norah O’Donnell leaving CBS Evening News?

While Norah O’Donnell is leaving the Evening News anchor desk, she is not leaving CBS.

“After this year’s election, I’ve decided I will be leaving my role as anchor and managing editor of the CBS Evening News to take on a new position at the network,” O’Donnell said in a statement published by CBS. “We just celebrated an amazing five years together. I love what I do, and I am so fortunate to work with the best journalists and people in the business.

“But I have spent 12 years in the anchor chair here at CBS News, connected to a daily broadcast and the rigors of a relentless news cycle. It’s time to do something different,” O’Donnell continued. “I will continue to contribute to Evening News and all of our news broadcasts, including ’60 Minutes.'”
