A special prosecutor a.) must be approved by the President and b.) appointed by the Attorney General.
Good luck with that.
So, how did the Special Prosecutor get appointed for the Watergate investigation?
Seems like Richard Nixon, President, and John Mitchell, Attorney General, would have stood in the way, according to this take on the enabling legislation...
And Nixon only lost 18 and half minutes of a tape recording. Is this not VASTLY more huge?
