In a first for Presidential transitions, it's now apparent that much of what Obama was doing between the election and the inauguration was intended to sabotage the incoming administration.
If moles in the various agencies are to leak timely damaging information, they have to be able to find it first.
So Obama allowed the NSA to let all those other agencies have access to RAW unfiltered unredacted intercepts. This is a huge expansion of the snooping, and a real threat to privacy. But the Dems don't care, because it's needed to undermine Trump.
Remember when Obama was going to be the most transparent administration ever? So much for that...
