There's no debate about Trump's slush fund. Hillary was always smart. Who do you explain the 88% drop in donations by 2019?
Easy. Once they were out of power, the donators who believed their donations were granting them access quit. They believed it was buying them access. The corruption charges require proof of that.
Trump got huge illegal donations from foreigners in his inauguration ceremonies. Did they get a payoff? I don't know but they did it for possible payoffs. Many world leaders who came in to talk to Trump, opened with telling him they stayed in his overpriced hotel. Did they get a payoff?
Clinton was not getting paid by the Clinton foundation. He was not profiting off those donations. I am sure they thought he would look on them more favorably. That does not make it so.
