I haven't followed this closely. What are the reasons that people doubt this? Michelle wouldn't comment unless she had good sources. The NIN sounds believable to me.
I don't really know what the story is yet, but it happened on 7/13 and was reported by NEIN several days later. I also heard a radio report that it was confirmed a few days after that. I wish I knew the source, but I didn't think much about it other than I was glad it was confirmed. To my surprise the FBI denied it. Oklahoma City has had known middle eastern conections for years. What's going on? Are the American people being strung along again because of political nonsense? Isn't that the primary identified reason for 9/11?
