CBS Evening News anchor John Dickerson has abruptly announced his exit after 16 years with the network. "Local news: At the end of this year, I will leave CBS, sixteen years after I sat in as Face the Nation anchor for the first time," Dickerson, 57, wrote via Instagram alongside photos from throughout his career on Monday, October 27. "I am extremely grateful for all that CBS gave me - the work, the audience's attention and the honor of being a part of the network's history - and I am grateful for my dear colleagues who've made me a better journalist and a better human. I will miss you." Dickerson did not provide a reason for his departure, nor did he mention any plans for the future. CBS News president Tom Cibrowski said in a statement that Dickerson "epitomizes the very best of journalism," USA Today reported.

Dickerson joined CBS in 2009 and hosted the network's public affairs program Face the Nation three times that year before later taking over as the host from 2015 to 2018. He also became CBS News' political director in 2011. Following his departure from Face the Nation, Dickerson was named the new coanchor of CBS This Morning. He remained in this role until January of this year, when he and Maurice DuBois became the coanchors of CBS Evening News, replacing Norah O'Donnell. CBS announced the decision to move Dickerson and DuBois, 60, to the evening news in August 2024, revealing that O'Donnell, 51, would have a bigger role as a CBS News senior correspondent.

"Norah's new role will give her the opportunity to contribute across CBS and Paramount, allowing us to see more of the groundbreaking stories and interviews that have been the hallmark of her career. Her superpower lies in her ability to secure and deliver big interviews and newsmaking stories that set the news cycle and capture the cultural zeitgeist. We look forward to elevating and showcasing Norah's reporting now and in the future." McMahon continued, "With Norah's decision, we began reimagining and redesigning the Evening News. The strength of CBS News has always been in its ensemble of journalists, both in front of and behind the camera, and our goal with John, Maurice, Margaret and Lonnie at the Evening News is to elevate the best in their fields every night for our viewers. In addition to this ensemble team, we look forward to welcoming '60 Minutes' correspondents to file for the 'CBS Evening News' when they have news to break; for decades this was routine, so it will be again." The Most Dramatic 'Today' Show Exits Over the Years: Hoda Kotb and More Dickerson's exit from the network also comes after former New York Times journalist and cofounder and CEO of The Free Press, Bari Weiss, was named CBS News' editor in chief earlier this month. Paramount acquired The Free Press as part of the move. "We are thrilled to welcome Bari and The Free Press to Paramount and CBS News. Bari is a proven champion of independent, principled journalism, and I am confident her entrepreneurial drive and editorial vision will invigorate CBS News," David Ellison, Chairman and CEO of Paramount, said in a statement. "This move is part of Paramount's bigger vision to modernize content and the way it connects - directly and passionately - to audiences around the world."
