By bypassing the existing oversight protocol, the administration has made it impossible to know whether this limit, or indeed any limit, is in fact observed.
That is why this nation was established with a President instead of a King.
Does it say in the constitution that the only due process for search and siezure is via court warrant? As far as I'm concerned, the President has the constitutional right to implement this program, which is MUCH milder than what we have done in wars past. Several Supreme Court rulings have UPHELD this power.
Seems to me that the Prez allowed many members of Congress to review the program on a regular basis. There is your check. Are there no gov't programs that deserve to be hidden from public view?
