NEW YORK (AP) - Veteran newsman Ted Koppel says NBC hasn't done Brian Williams any favors by shuffling the newsmagazine "Rock Center" around its schedule.

Koppel, the former host of "Nightline," has a story on "Rock Center" Friday about minors held in solitary confinement in adult prisons. Koppel does about four or five stories a year for the newsmagazine.

Now on Fridays, the show has been on four different nights since it debuted on Halloween 2011.

Koppel said just when people figure out when the show is on, it's moved. He said Williams deserves more support.
