CBS News is entering into a "new era." A recent staff shakeup at the network is bringing in new co-hosts for "CBS This Morning." Gayle King will remain at the show, but Norah O'Donnell and John Dickerson will move on to other positions. O'Donnell will head to "CBS Evening News" this summer, becoming the show's anchor and managing editor. She has co-hosted "This Morning" since 2012. Dickerson will become the lead anchor of political events for CBS.
