ABC announced its plans for the January 3 Iowa caucus coverage today. The day will begin with a special edition of Good Morning America, anchored by Diane Sawyer and Chris Cuomo, broadcast from Des Moines.

Charles Gibson will host special reports during primetime as the results come in, and will be back for Nightline with Terry Moran. George Stephanopoulos will be on hand as well for the all-caucus edition.

ABCNews.com will have full coverage all night as well.

Earlier this week, NBC/MSNBC and CNN released their caucus coverage plans.
