I believe those are accepted facts. The June application for a wiretap was denied. The October request was granted and the tap was made. For all we know it is still active, although that seems unlikely.
The wiretap applications could be declassified by Trump, although they might be misleading since they were advocacy documents. The results of the wiretap are in Obama's non-exclusive possession...ready to be leaked when a news cycle demands it.
One thing all Americans dislike is the government spying on political enemies. The Democrats will claim it was justified, but only because they reflexively defend their own, no matter what. Can you imagine the outrage if Trump had tapped Chuck Schumer? It would be insane.
Hopefully, Trump will press this one all the way, to the last person involved. This is a battle that honest Americans will want Trump to fight. The goes to the very core of trusting the government.
Wow...since it was made in October, the motivation was almost certainly political!
