Sadly, this is really nothing new.
Lest we forget the 900+ FBI files, this sort of abuse has been going on far longer.
Hillary was going full bore when Bill was POTUS, and even then amassing the "opposition research" using government means or the raw material even FBI background investigations had generated, (need I note?) in violation of Federal Law.
That the practice of using taxpayer funder Federal investigatory agencies to conduct political research for the purpose of affecting election outcomes, or the illegal use of Government 'protected' documents to affect those outcomes has been going on for a long time is evident. Look no farther than the sealed divorce records revealed and used against Obama's opponent in his Senate election run. Without that toehold, (Senate seat) we might live in a different country today.
We have laws against all of this. It is past time to enforce them.
