Maurice and Kristine alternate anchoring from the studio for the 5 and 11pm newscasts. The other anchor broadcasts from home. At 6 Dana Tyler broadcasts from home and either Maurice or Kristine broadcasts from the studio.
That’s possible although Katy would still only have the 2pm hour if Chuck was at 1 and Nicole started at 3. Also why is Brian Williams co-anchoring with Katy? Possible move to afternoons so Shep Smith can take his spot if/when he join?
