Veteran newscaster will leave World News in September, ABC says

News anchor Diane Sawyer will step down from ABC’s World News this September.

“After wonderful years at “World News” I decided it is time to move to a new full time role at ABC News,” said Sawyer.

Beginning September 2, weekend World News anchor David Muir will assume her position, becoming Anchor and Managing Editor of the program. The World News switch is not the only change—George Stephanopoulos, anchor of GMA, will become Chief Anchor for ABC News.

Congrats to my friends @DavidMuir & @GStephanopoulos – big days and stories ahead for all at @ABC !

Sawyer, who once anchored Good Morning America and Primetime, will continue to appear across ABC platforms, tackling, “big issues and extraordinary interviews,” said ABC.

“I’ll be joined by an incredible team of journalists dedicated to enterprise reporting, innovative approaches to breaking news and new ways of thinking about big issues and events around the world,” Sawyer said. “I can’t wait to continue bringing more of my specials to prime time and appearing on all ABC News broadcasts, as well.”
