He has been with the Secret Service about 7 or so years. President Bush thinks he is a good agent but it seems he lost his cool while trying to catch a flight to Texas. He then turned this into a media war against American, possibly because he realized he had already burned his bridges by immature belligerent behavior in front of witnesses.
He's been with the SS for 7 years, but I don't believe he's been on the Presidential detail that long -- the question about his possible "promotion" is a good point. Conversely, his demotion, at any time after 9/11, might have created a complaint to CAIR, I would venture. Another unanswered question is how this guy, obviously Arab, came to be flying commercial on Christmas, a day I'm sure the airlines were doubly apprehensive, and on American Airlines, who has lost 2 planes to terrorism, and very nearly a third (shoe-bomber) the week before? A setup?
What I chuckle about is Bush's remarks on Saturday that on 9/11, when he made his decision to go after the perpetrators, he didn't "talk to any lawyers" -- a remark designed to appeal to conservatives, but one that's being contradicted by his support of this agent. Double-speak?
