CNN's "Piers Morgan" ending in three weeks

CNN’s Piers Morgan will officially end his primetime show at the end of the month and will be temporarily replaced by alternating hosts, including Bill Weir and Jake Tapper, network sources told POLITICO on Friday.

Morgan’s departure from primetime sets up a head-to-head trial-run between two ambitious anchors for the coveted 9 p.m. slot. Weir, the former ABC Nightline anchor, is scheduled to anchor “Piers Morgan Live” for the week of March 17. Morgan will return the following week for his final broadcasts, after which Tapper is scheduled to take the reins.

From there, CNN will test Weir, Tapper, and possibly other hosts until deciding what to do with the 9 p.m. hour. The network may ultimately decide to split up the hour or give it over to non-news programming.
