Well, no actually, it does not. Nor does it apply to non-Muslim citizens, or white citizens, or any other types of citizens.
And excuse me, but you were just "recently" made to wonder about this? Only recently?!?
We apparently decided after 9/11 that airports and any place within 100 miles of the border were going to be Constitution-free zones, where the laws around search and seizure just do not apply to anyone.
The following happened to me, for instance, in an airport in 2006:

This is one of those things that kills me -- those of us whining about all this, especially under Obama, were "shrill" civil libertarians. But then Trump came to power.
Now that this crap is happening under Trump, and it's happening to ACLU lawyers and doctors and newspaper journos and so on (cue the scary music), it's suddenly a crisis, and people's hair is on fire.
It was a crisis over a decade ago, when we just abandoned the Constitution in airports and at borders. And the warning that civil libertarians gave, which was roundly ignored, was "wait until the wrong person gets hold of this power."
