Good request. I don’t think credibility is with the lobbyist. If info was delivered, and oppo research is sought by all, why wasn’t it used? The polls showed Teump in arrears. Logic tells me info would have been used early and often after both nominations.

My guess is they figured that damaging information about corruption at the DNC wouldn’t have gotten much attention at all. In fact, it wouldn’t even be considered NEWS to most people.
