CBS News chief Jeff Fager is upset that some of his executives are leaving the network for NBC, which is gearing up for its new prime-time newsmagazine, reports the New York Post.

The new show, "Rock Center with Brian Williams," is “the first meaty prime-time news show to launch on a broadcast network in years,” the story reports, making it an attractive destination for producers and associate producers.

The show is run by former "60 Minutes II" executive producer Rome Hartman, who is said to have hired three associate producers from CBS’s "60 Minutes," the story notes. The new show has also reportedly attracted talent from CNN and ABC.

Fager is trying to block some departures, the piece adds.

Said a source: “There was one person from CBS News who was offered a job and CBS kept him, but there are still some people in play.”

CBS appears to be downplaying any competition for talent. A source at the network is quoted in the story as saying: “These are folks who wanted producer jobs, and there weren’t any. They wanted to go to the next level, and we wish them well.” Officially, neither CBS nor NBC would comment to the Post about the story.

Former CBS “Early Show” anchor Harry Smith is among the on-air personalities who have joined the new NBC show.
