ABC News President Ben Sherwood made the following announcement today about new roles for Rob Nelson and John Muller:

Please join me in congratulating Rob Nelson and John Muller on new roles at ABC News.

After nearly three years as co-anchor of World News Now and America This Morning, I'm delighted to announce that Rob will move dayside as a correspondent reporting for all platforms and programs.

Rob distinguished himself on the overnight leading the network's coverage of the Japanese tsunami, a story that broke just before WNN airtime.

He also led a two-hour ABC News Special Report last summer following the late-night theater massacre in Aurora, and he's reported often for the weekend editions of World News and GMA.

As overnight anchor, Rob's reporting, grace and humor infused each broadcast with a winning style he perfected over many years covering the Big Easy at The Times-Picayune and WWL-TV, New Orleans' top-rated station.

I'm also happy to announce that John Muller will become the new overnight anchor for WNN and ATM.

John is a seasoned anchor and terrific broadcaster. Before joining us in 2011, John spent 11 years as the anchor of the Emmy Award-wining PIX 11 Morning News in New York City.

He has reported on a great variety of stories for all our programs and platforms including the Valedictorian Murder Trial in Michigan and the Mayan Apocalypse (with an "exclusive" live hit from Times Square to prove the world had not come to an end).

We expect great things from John and his co-anchor Diana Perez and I'm confident they'll keep up the strong tradition of breaking news and engaging conversation on our overnight programs.

Please join me in wishing Rob and John the best of luck in their new assignments.

Ben
