What’s encouraging to me about the Mueller investigation is that Trump and the shady people in his orbit did business for years while never expecting the level of scrutiny they are getting now. We know that Cyrus Vance, New York District Attorney, considered filing charges against Ivanka and Donald Jr. in 2012 for misrepresenting the status of sales for one of the Trump buildings, misleading potential investors. After two years of investigation Vance ended the case without charges, and he later received a large campaign contribution from the Trump organization.
That isn’t going to happen in the Mueller investigation. Mueller isn’t running for anything. If illegal behavior happened, I believe he will call those responsible to account.
