Uh, right. The same guys who's "expert" opinion was that perjury and obstruction of justice are not "high crimes and misdemeanors" justifying impeachment - when committed by Bill Clinton.
Yeah, I know. And who had no problem with how the government handled Waco or Elian Gonzales, or the Clintons gathering FBI files of their political opponents, or (as you mentioned) lying under oath in a deposition and before a grand jury. Funny how this works.
There is no doubt in my mind that the NSA program is constitutional. It is reasonable to monitor international communications involving suspected terrorists even without a warrant. So, there is no Fourth Amendment problem. And in any event, it is part of the President's inherent power as commander in chief under Article II. Especially when we are already at war with the very people that we are monitoring abroad. The Constitution was never intended to be a suicide pact.
