Hitlary Clinton is the one that sent those Black Lives Matter(Otherwise known as Black Lives Only Matter When They Were Killed By Cops) to Sanders campaign rally..Sanders knows it, this might be some nice payback on his part
I have been waiting for someone to say what you just said. It is so obviously Hillary.
It's so ironic that I mentioned this very thing to someone the other day because I just had a feeling that Hillary had something to do with it. I just saw on the internet today that the BLM group is funded by George Soros - who is supporting none other than Hillary!
