From the transcript:
"It never occurred to us that the commander-in-chief of the American armed forces would abandon 50,000 of his citizens in the twin towers to face those great horrors alone, the time when they most needed him."
He did use 'abandoned' and as you point out, the initial estimates were that around 50,000 people were in the buildings.
Did anyone see what was posted in the post, about attack on Nov. 13th on the Sears Tower?
The title was in breaking news, but the article was pulled by the AM.
I presume it was just some uncorraborated statement, but I wonder if anyone here has seen anything about it?
