Doesn't mean a thing. This is how the Dims play politics and keep their goobers involved. If they have nothing else going on,they announce a lawsuit to rally their troops and bring the donations in again.
And it has to be said the alleged Republican Party does the same thing these days.
The fact is if any of them had anything they had any hope of proving they would be filing criminal charges. They don't have any evidence to prove anything,so they go with innuendo and try to influence public opinion. This rallies their drones and the hope is they can fool enough of the "I only vote once every 4 years for whoever has the cutest candidate/wife" voters that vote on emotion instead of knowledge/political awareness.
Chances are none of this is going to get any closer to a courtroom than on the headlines of a newspaper someone leaves there.
