Obama Quietly Issues Ruling: It's Legal For The FBI To Access Phone Records

But this is fishy all around. The Executive doesn't have the ability to make things legal or not legal (especially retroactively - and they do have the ability to pardon which in a way makes that moot).
But from further reading it looks like the Obama "Office of Legal Counsel" wrote a brief stating that the searches were legal. However this doesn't make it so. (an extension of the whole John Yoo mess). What this is is a huge grey area w/o black letter law. Anyone can say its legal/illegal but the courts will still ultimately decide who's right.
Hell if he could do that than why have a ruling at all on political contributions.
The fact that they're doing such should trouble anyone with half a brain, but it also comes as no surprise at this point.
