Because Hillary egged her on.
Probably Soros not Hillary. While she and Bill will not be touched by a Trump administration, being a former president and first lady....The real people and groups behind many of the former presidents are fair game. The goal is disruption and possibly fighting to delegitimize Trump and keep him from investigating and taking those people and groups down by any means possible. If this administration does not prosecute the people and groups behind the globalist....they are just as powerful the moment they get back in power.
There is only one chance left for this country and it is a slim one.
