Trump was talking about alleged disinformation directed at him and other Republicans. But WOW does that quote explain everything you need to know about his approach to the presidency and life.
(Sidebar: One can only hope that Trump was unaware that his quote was a near-replication of this infamous line from Nazi Joseph Goebbels: "If you tell a lie big enough and keep repeating it, people will eventually come to believe it.")
Trump has spent a lifetime -- in business and politics -- repeating exaggerations, half-truths and outright lies to make himself look good.
