From what I have read:
The FISA court authorized this wiretap.
The real question is what reason was given to the court to obtain the wiretap and when. Before the election? After?
Keep in mind, there was almost no chance given for Trump to win.
We need a timeline on this.
Wiretapping the nominee of one’s opposition party leading up to the election should be a criminal offense in our republic. This is truly Nixonian...
The FISA Court initially denied the tap. Only after the warrant was narrowed did they allow it. The issue here is once they allowed it how far was it expanded beyond the scope of the narrowed warrant? In either case the tapping of political opponents is illegal but this should not surprise anyone considering the history of this admin and targeting political opponents such as the Tea Party. Obummer plays by Chicago rules and a few officials are sitting in jail right now playing those rules.
