NEW YORK (AP) — ABC News is making leadership changes behind the scenes at its top two broadcasts.

The network announced Tuesday that Tom Cibrowski (sih-BROW-skee), the top executive behind “Good Morning America” as it passed by NBC’s “Today” show in the ratings, will become a top deputy to news division President James Goldston. As senior vice president of news programs, news gathering and special events, he’ll report to Goldston and promote coordination at all of the network’s broadcasts.

Michael Corn will replace Cibrowski as senior executive producer at “Good Morning America.” He’s been the top producer at Diane Sawyer’s “World News.”

With David Muir to take over next week as the evening show’s anchor, Almin Karamehmedovic (care-uh-meh-MEHD-oh-vich) will become that show’s top producer.
