He should’ve said it could go to the Clinton Foundation and then turn around and make a joke about it.
Next headline we will read. “Sanders cancel debate with Trump” saying he needs that money to support his bid for POTUS.
He should cut a check for $.25 to the Clinton Foundation and say that's because they're only worth 2 bits. Hillary + Huma = 2 bits (did I spell that right LOL) then send the remaining millions to the Little Sisters of the Poor.
I can just see Bernie supporters throwing quarters at Clinton rallies yelling “2 bits 2 bits” Great street theater.
