Weird..
I find the whole thing weird because we've known they've been doing this for about a decade. I mean, this is not a surprise, I believe the Reg itself reported various law enforcement agencies (and possibly the NSA) where vacuuming up cell phone records, internet traffic, etc from US citizens. Also the "we'll get a warrant later" wiretaps have also been reported on. There's no surprise this hasn't stopped with a change of President, these things have always had broad bi-partisan support. Left or right, governments don't trust the people that elect them and are supposed to be represented by them.
Interestingly these things are actually completely illegal in the US. The US Constitution specifically states a search warrant can only be granted to investigate a person suspected of committing a crime (talking to someone from a different country is not as far as I know a criminal activity) and can only be awarded by a judge. This was to counter exactly what is happening now. Back in the good old days of British Colonies, British soldiers would write their own search warrants then invade people's homes without warning. Secret warrants issued by secret courts granted after the search has been executed seems to fall outside of these requirements.
Congress is not allowed to simply create a law that bypasses this, it would require a re-write of the Constitution, possibly by creating an ammendment. No small thing given this is one of the document's founding principles.
Basically anyone that engages in this practice is breaking the law, any law that permits it is unconstitutional and therefore invalid, and the legislative bodies that created, voted on and passed these laws have violated their oaths of office (to protect the Constitution), including the President at the time (G.W.). I'm not sure what punishments are suitable for willfully violating your oath of office or violating constutional law, but it ought to be every bit as final as leaking very well known non-secrets to the press.
