Did Obama Pay Off John Roberts?

Did our President pay off our highest court's chief justice on the Obamacare ruling? I would like someone to investigate that. I keep going back, in my mind, and thinking over how all of the other supposed non-leftist justices voted it down, but Roberts voted for it. Did Obama or any of his people talk with Roberts or any of his people from the time Obamacare was deliberated in the court, to the time the ruling was announced? If they did, that's a crime!
