Jeff Greenfield to leave CNN

CBS News has again raided CNN in an effort to beef up its staff in the Katie Couric era.

Jeff Greenfield, a senior political analyst for the cable network for nine years, has agreed to join CBS as the presidential campaign gears up. CBS recently hired general assignment reporter Kelly Wallace and technology correspondent Daniel Sieberg away from CNN and has made CNN anchor Anderson Cooper a “60 Minutes” contributor.

Greenfield worked as a media analyst for CBS in 1980, but he made his reputation during 14 years at ABC, where he reported for such programs as “Nightline” and “World News.” The deal was confirmed by people familiar with the matter who declined to be identified discussing a personnel move that has not been made public.
