and why Michelle visited him.
She visited victims of the bombing in two Boston-area hospitals, including the one where the Saudi was being treated. There are pictures of her visiting other patients as well.
You do understand that when a person has a 212 3B that the Secret Service cannot allow her to visit him. So, who cleared it for her to do that?
The other patients were just a cover so that she could go see this guy, I am sure. Unfortunately, the media is so in the tank that the American people have not even begun to hear the truth yet.
