NEW YORK - ABC's "Good Morning America" is losing co-anchor Charles Gibson and now it is losing its chief executive behind the scenes, too.
Ben Sherwood, executive producer of the morning show, said Friday that he will resign this fall to move to Los Angeles for family reasons.
No replacement has immediately been named.
Sherwood led "GMA" to ratings gains behind the anchor team of Gibson and Diane Sawyer. But after narrowly missing an opportunity to pass NBC's top-ranked "Today" show last spring, it has fallen further behind.
Gibson will leave at the end of June to concentrate on his "World News Tonight" anchor job, which he assumed Monday.
The network is spending the summer looking at cast additions for "GMA."
