Ken Starr warns Trump against firing Mueller

Former independent counsel Ken Starr called the prospect of firing Justice Department special counsel Robert Mueller an "insult to the Founding Fathers" in a Washington Post op-ed published Thursday night.

Starr, whose investigation into former President Bill Clinton began with a look into the Whitewater real estate deal but eventually grew to cover the Monica Lewinsky scandal, wrote of the importance of having an "outside investigation" that can skirt potential conflict of interest concerns when investigating matters on the executive branch -- no matter whether suspicion of the President falls "rightly or wrongly."
