Diane Sawyer Tells Her Viewers She's Leaving 'World News'

ABC's Diane Sawyer told her viewers on Wednesday about her decision to leave the anchor chair at "World News," and she brought on her successor, David Muir, to help her out.

Sawyer is stepping down from her post in September to concentrate on specials and big interviews. Muir will become the new anchor and managing editor of "World News," though, in a break with tradition, he will not be the chief face of the network during major stories. That role will instead go to George Stephanopoulos, who has been given the title of "chief anchor."

On the broadcast, Sawyer said she loved "every night I get to spend with you," adding, "and I am so happy that someone you know well is going to be at the helm of ‘World News.'"

Muir then paid a fulsome tribute to Sawyer, calling her the "captain" of the broadcast. She noted he was filling in for her on Thursday night.

"There's no turning back," he quipped.
