"CBS Evening News" is going through another shakeup.
John Dickerson, who took over as co-anchor of CBS' evening news broadcast in January following the departure of Norah O'Donnell, is leaving the network at the end of the year.
Dickerson shared the news in an Instagram post on Monday, Oct. 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," he wrote. "I will miss you."
Dickerson, who also serves as CBS News chief political analyst, did not share a reason for his departure. He will continue to co-anchor the "CBS Evening News" until the holidays, the network said.
In a statement, CBS News president Tom Cibrowski said Dickerson "epitomizes the very best of journalism," adding that "we'll have plenty of time to thank him for his work here and honor his contributions to our success" before he leaves at the end of the year.
