Stephanopoulos Starts Early Shift As 'GMA' Co-Host

George Stephanopoulos is tackling the early shift in his new job co-anchoring ABC's "Good Morning America."

Robin Roberts termed it "the dawn of a new day" as she welcomed Stephanopoulos beside her at the "GMA" anchor desk on Monday.

He's making the jump to weekday mornings from New York after seven years based in Washington hosting the Sunday "This Week" political interview show.

At "Good Morning America" he's replacing Diane Sawyer, who next week will take over ABC's dinner-hour "World News" from retiring anchor Charles Gibson.

Stephanopoulos will stick with his duties on "This Week" until his successor is named.
