ABC News is implementing a number of lineup changes among key production executives. TVNewser reports that “Good Morning America” senior executive producer Tom Cibrowski is receiving a promotion to senior vice president of programs, newsgathering and special events.

With Cibrowski’s promotion, “World News” executive producer Michael Corn will take his place on “Good Morning America,” the publication notes. At “World News,” “Nightline” executive producer Almin Karamehmedovic will take Corn’s place, the story adds.

“Karamehmedocvic, a native of Bosnia and Herzegovina, has deep roots in international reporting for ABC,” the publication reports. “In 2001 he was one of the first journalists to gain access to Tora Bora, Afghanistan, where Osama bin Laden was holed up, and in 2003 was a U.S. Army embed during the invasion of Iraq. A replacement at ‘Nightline’ will come later, we hear.”
