The government also doesn't let people conduct sensitive or classified conversations over un-certified protocols or devices. Unless the NSA was participating in the bluetooth encryption standards decisions they aren't going to allow those devices to be used by the President or VP. IMHO though, it's probably more that there were security trade-offs made when developing the standards and the government isn't OK with those types of trade-offs. It doesn't mean they're horrible, just that they aren't verified to be secure enough for sensitive governmental purposes.
