MSNBC Taps Kornacki as New Host of 'Up'

MSNBC has named Steve Kornacki as the new host of its weekend morning program Up. He replaces Chris Hayes, who will move over to primetime, hosting the 8 p.m. hour on weekdays beginning April 1.

Kornacki was previously the cohost of the network's mid-afternoon roundtable program, The Cycle, and is also a senior political writer for Salon.com. Jonathan Larsen will continue as executive producer of Up.

"I give so much credit to the Up team who created appointment viewing on the weekends for us and some of the smartest conversations on television," said MSNBC president Phil Griffin. "Steve has a great political mind and his ability to connect with viewers made him a natural fit to continue driving that dialogue."

Up airs Saturday and Sunday from 8-10 a.m.
