The whole world praised Ahmed for his scientific genius at being able to take a clock apart and putting it back together in a small metal case. It looks like Obama was a little worried that he had invited him. As you can see security was tight. Obama was closely flanked by two security personal keeping a close watch on Ahmed Mohamed every move. Of course Ahmed left his clock at home. I guess he couldn't get it thru White House security. Ahmed's entire family is highly radicalized.
