LOL, that will stand as the most idiotic claim in this discussion!
If it's been infringed, then the power no longer exists. If it's still a power, then there has been no infringement. If it's a constitutional power, it can not be constitutionally infringed. Basic con law.
Even the FISA court itself has concluded that the President has the inherent constitutional power to conduct warrantless searches to obtain foreign intelligence information. If he has the power, then it hasn't been infringed.
False. Look up "infringe".
