CNN slotted new anchor Jake Tapper's upcoming show for 4 p.m. on weekdays, cutting Wolf Blitzer's "The Situation Room" back one hour, a CNN spokeswoman told TheWrap.

Tapper, lured away from ABC News in December, was CNN boss Jeff Zucker's first major hire since taking charge of the network. Now, with his own show coming in March, Blitzer's program will but cut from three hours to two as it moves to the 5 p.m. to 7 p.m. time slot.

A CNN spokeswoman told TheWrap Tapper's show has no specific starting date yet because it is still in development.

Last month, Turner Broadcasting posted LinkedIn job openings for a senior producer at a new daily program called "Tapper."

And on Monday, CNN named Federico Quadrani, MSNBC's executive producer of "Jansing and Company," as the show's new executive producer.

Choosing Quadrani -- who served as an Emmy-winning producer for NBC's "Today" show from 2003 to 2009 --is one of Zucker's higher profile hires as the former "Today" producer attempts to replicate his morning show success at CNN.

After taking charge of the show in 1992, Zucker led "Today" to its ratings highs before Katie Couric's departure for CBS.  The subsequent exit of Meredith Vieira, who replaced Couric, made it vulnerable to rival "Good Morning America."

Late last month, CNN announced that it had bought "20/20" anchor and former "GMA" host Chris Cuomo to lead a new morning show with Erin Burnett.
