Veteran news producer Tom Bettag joins CNN Worldwide as senior executive producer of "State of the Union with Candy Crowley" and "Reliable Sources."

Bettag will oversee the Sunday public affairs programming lineup, effective immediately.

Crowley took over the anchor chair on "State" this month as the program's length was cut down from four hours to one.

In Bettag's more than four decades in journalism, he has served as executive producer of "CBS Evening News With Dan Rather," of ABC's "Nightline With Ted Koppel" and of "Koppel on Discovery" on the Discovery Channel.
