ABC's Good Morning America moved ahead of the usual weekday morning leader, NBC's Today, on Monday of this week, according to Nielsen Research. GMA, which aired the first part of an interview with Iran's Mahmoud Ahmadinejad conducted by Diane Sawyer, attracted 5.7 million viewers, while Today claimed 5,418,000. ABC News chief David Westin sent public congratulations to Sawyer, who a week earlier had interviewed Syrian President Assad in Damascus. Westin described her work as "breathtaking."
