Exclusive: TVNewser has learned World News with Charles Gibson will address the controversy over his and George Stephanopoulos's performance in last night's Democratic primary debate in Philadelphia.

World News executives assigned the story to David Wright, who covers the Obama campaign. Insiders tell us the majority of the soundbites reflect a negative view of the debate moderators.

> Update: Wright's story included soundbites from locals in Philadelphia, some of the comments from ABCNews.com received, and a mention of "an organized campaign by the liberal group MoveOn and others to send a message to ABC."

After the story, Gibson said, "the debate over the debate has been heated, it continues at our Website, ABCNews.com. And we appreciate all the comments sent in, from all points of view."
