That's right.
We don't know.
It is 'said' to have named Trump?
Who said that?
From your link:
FISA wiretap requires no showing of a crime, just evidence amounting to probable cause that the target of the wiretap is an agent of a foreign power.
I'd say he fits the standard for probable cause.
If there is a FISA court warrant naming him, he could prove that, no?
If there isn't there should have been considering his and his people's cozy relationship with the Russians.
He said that Obama tapped his phone and never said anything about any warrant, or the FISA court.
If that were true, it would be a big **** deal.
Then an hour later he's Tweeting about The Apprentice.
