"We are extremely satisfied with and proud of our newsgathering operation. No outside arrangement is being negotiated," the spokesperson said.
CBS News issued the statement in response to a story in the New York Times that reported CBS has been discussing a deal to outsource some of its newsgathering operations to CNN.
The newspaper, citing two unidentified executives as sources, said the talks involved cutting CBS' news operations while retaining prominent figures like CBS Evening News anchor Katie Couric.
The Times said that over the past decade, CNN had held talks with CBS News and ABC News about possible joint ventures.
