Donald Trump lies. Telling untruths is not merely second nature to him; it is of the first order, automatic. He lies as naturally as he breathes.
From his claim to being a great businessman and dealmaker to calling himself not the worst president in U.S. history — which he is, by far — but the best, Trump has spewed a firehose of falsehoods to the public. But he has never reserved his lying only for his political opponents.
