Trump looks at his campaign contributions as his personal slush fund - if anyone doubts that, let me remind you that Trump's "foundation" was closed down because it was being used as a Trump Family checking account, instead of actually giving money away. So this news, while disappointing, is not surprising at all. Trump's "campaign manager" (Pascale) has become a multimillionaire over the past few years running Trumps "campaign" - from nothing to $14M+ net worth. We saw his tendencies, publicly, when the "inauguration fund" sort of just disappeared, more than $100M - some of it was spent on the actual event, of course, but not enough - not even close.
If we're allowed to investigate Trump and his Crime Family if Biden wins in November, financial crimes will one of several categories we should look into. The grifters can't keep their hands out of the coffers, and it won't stop. Should Trump win in November, expect it to continue, exponentially.
