Diane Sawyer Steps Down As Anchor of ABC's 'World News'

Diane Sawyer will be stepping down as an evening anchor from ABC World News and 20/20 anchor David Muir will takeover on September 2.

“At the end of last year Diane Sawyer started a conversation with [former ABC News president Ben Sherwood] 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,” ABC News president James Goldston wrote in an e-mail (via the Washington Post). “As much as she loved leading World News to new heights…Diane decided that now is the moment to concentrate full time on tackling big issues in new ways.”

Diane, 68, has been with ABC News for nearly 25 years.
