Stephanopoulos is most well-known as the chief political correspondent for ABC News — the news division of the broadcast television network ABC — and a co-anchor of ABC News's morning news program, Good Morning America (GMA). He was previously the host of This Week, ABC News's Sunday morning news program. He is the primary substitute anchor for ABC News's flagship news program, World News with Diane Sawyer.
In recent years he has co-hosted ABC News's special live coverage of political events with Charles Gibson and Diane Sawyer, and has appeared regularly on GMA, World News, and launched "George's Bottom Line", an ABCNews.com blog.
Prior to joining ABC News, he was a senior political adviser to the 1992 U.S. presidential campaign of Bill Clinton and later became the White House Communications Director for two years, before being replaced by David Gergen after political fallout from the historic mid-term election of 1994, in which the Republican party took over the U.S. House and Senate.
He is married to Alexandra Wentworth, an actress, comedian and writer. The couple have two daughters, Elliott Anastasia Stephanopoulos and Harper Andrea Stephanopoulos; the family lives in New York City.
In 1995, after a collision with a parked vehicle as he was pulling out of a parking space in front of a restaurant, Stephanopoulos was arrested and charged with leaving the scene of an accident and driving with an expired license and license plates in the Georgetown neighborhood of Washington, D.C. Only the charge of leaving the scene of an accident was subsequently dropped.
Along with a number of other notable Greek Americans, he is a founding member of The Next Generation Initiative, a leadership program aimed at getting students involved in public affairs.
