George Stephanopoulos, who has co-hosted Good Morning America on several occasions over the years, on Monday night served as anchor of ABC's World News with Charles Gibson. From what I can recall, this is the first time the long-time adviser and strategist for Bill Clinton, and Dick Gephardt before that, has anchored World News -- or World News Tonight as it was previously named.
The screen shot to the right is from the top of tonight's (June 4) newscast.
