Juju Chang Moves To 'Nightline,' Josh Elliot In At 'Good Morning America'

"Good Morning America" newsreader Juju Chang is moving to "Nightline," ABC announced Tuesday. She will be replaced by ESPN's Josh Elliott.

Chang will become a special correspondent and fill-in anchor on the show. She had been the newsreader for "GMA" since December 2009, the last time the show was overhauled.

Elliott has been at ESPN since 2004. He's currently an anchor on "Sportscenter."

ABC News President Ben Sherwood sent a memo to staff about Chang's move.

I'm writing to share some news about Juju Chang, one of our most talented and versatile colleagues.

Going forward, I've asked Juju to take a full-time role as a special correspondent and fill-in anchor at Nightline where she will contribute even more of the in-depth and insightful journalism that has always been her hallmark.

In her new position, Juju will play a leading part in a number of the 13 primetime hours that Nightline will produce this summer. She will also make major contributions to 20/20, World News and GMA - as she has throughout her 23 year career at ABC News. This move will be effective in the coming weeks.

Over the past 15 months as the news reader of Good Morning America, Juju has traveled to South Korea for an interview with President Lee Myung-bak, reported live from Haiti in the aftermath of the earthquake and, most important, as far as her sons are concerned, played baseball with A-Rod as part of GMA's "Living the Dream" Series.

In the coming days, I will share news about the next news reader at GMA.

In the meantime, please join me in thanking Juju for her leadership at GMA and congratulating her on her special role with the #1 program in late night.
