NEW YORK (WTVD) --
ABC News announced new roles Wednesday for Diane Sawyer, George Stephanopoulos and David Muir.Sawyer will lead new programming focusing on big issues and news-making interviews, Stephanopoulos will add Chief Anchor of ABC News to his "Good Morning America" and "This Week" duties, and Muir will become Anchor and Managing Editor of World News starting September 2.
In a news release, ABC News President James Goldston said Sawyer started a conversation last year about one day stepping away from World News and "devoting her boundless energy full time to a team which will create and commission original reporting, big ideas and interviews for all platforms."
"As much as she loved leading World News to new heights - with so much important, brilliant and impactful reporting and a number one finish in the May sweep - Diane decided that now is the moment to concentrate full time on tackling big issues in new ways," said Goldston.
Goldston said Stephanopoulos will be the lead anchor for major special events and breaking news at ABC.
And Muir will also continue to anchor 20/20 with Elizabeth Vargas and will play a key role in covering the biggest breaking news events as they happen.
"David has made his reputation reporting from the ground on every big story of recent times, and we know that when the big stories happen, wherever they happen, David will be there for us and our audience," said Goldston.
