Let's revisit the FBI findings on the Democrats precious, Hillary.
Under Oath Hillary Clinton, lied that there were no Classified emails on her unsecured, private server. James Comey said otherwise. She should have been criminally liable for both possessing or transferring Classified emails from a secured to unsecured system and then Perjury (Lying under Oath).
Had she been convicted as she should have been, she would have had her Presidential candidacy revoked. But of course, this did not happen because suspiciously, her husband, Bill Clinton, had a 45 minute chat on the back of a plane with then U.S Attorney General, Loretta Lynch, days before FBI were to conclude the FBI Investigation report on Hillary Clinton's email investigation.
So if Trump is to have a impartial investigation, then she, crooked Hillary and her husband, Bill Clinton, Loretta Lynch and James Comey, need investigating into what was discussed at the back of that plane and why suddenly, no criminal charges were to be brought about.
So it is not okay to dismiss the above and then say Democrats should decide on stuff for Trump, don't think so, they did not act holier than thou when it came to their precious, crooked Hillary.
