If you don't mind mildly offensive language, look up what Louis C.K. said about Trump when he was on with Stephen Colbert.  I agree with Louis on that.  On one hand, we have the head of the FBI, who served under 2 Presidents, and has never been accused of lying.  Maybe not the smoothest guy, but never a liar.  Then we have President Trump.  Trump fed the Birther movement for years.  Trump had to pay $25 million to settle the Trump University lawsuit.  Trump has been a proven liar time and time again in the months since he took office.  Who should the American public believe?  Yeah, not Trump.
