My guess is that he does.
It is also my guess that someone in the intelligence community is willing to talk to the current administration. All it takes is one.
I think it said somewhere in the article that Obama tried to get a wiretap on Trump but a judge denied it. I wonder if the judge and Trump had a talk. It's not hard to place a wiretap with a court order through the telephone company but there are other ways he could have been wire tapped if someone had access to some of closets with the telephone with the wiring blocks. All they'd have to do is know which pairs to clip their bugging device to. It would run on batteries or hours and they'd just sit outside in a monitoring post listening. I imagine the cell phone was first choice though. If it were tapped without approval it wouldn't surprise me if he tried another source. Only the ends justies the means to the lefties. As long as they don't get caught, it didn't happen.
