The article does not seem to cover that question. From previous discussions I have the impression that foreigners are not granted any constitutional rights at the border or even when in their home country (their communication can be freely intercepted). So the US is nowadays on my personal list of totalitarian states that I don't want to travel to. They definitely have better legislation and courts than Russia or North Korea, but in the end the decision is, as a foreigner you don't have those rights, the government does what it sees fit.
