I don’t know about that, I guess it is possible. But what Laura seemed to be saying is that the request went through AT&T and the NSA. schiff had the phone numbers and had the NSA provide the name of the owner of the phones.
I think anyone can obtain and attach a name to a phone number with simple online companies if Schiff already had the number. Only the NSA would have the conversations, of course. I am pretty sure this Schiff guy would at least have that thought in mind. Whether they turned him down or not, we don’t know. Maybe he went to one of crooked FISA judges that approved wiretaps under false pretenses against everyone who knew Trump.
