Asked about concerns Trump wouldn't honor list, Grassley says he has "heard a lot of misstatements and corrections by Trump" but has "never heard him accused of being a liar."
First, there's the sheer breadth and character of his falsehoods. Absurd exaggerations, mischaracterizations of his own past, distortions about his opponents, descriptions of events that never occurred, inventions personal and political, foreign and domestic, Trump does it all. [...] In this, he differs from other candidates, who usually have had one distinctive area of dishonesty that characterized them. Some hid things they were embarrassed about or thought would damage them politically, some deceived about their personal histories in order to paint a flattering picture of themselves, and others spun a web of falsehood to gain the public's assent for policies they suspected might not otherwise gain public support. But there has simply never been a candidate who has lied as frequently, as blatantly, and as blithely as Trump. Then there's the fact that even when Trump gets caught lying, he keeps on repeating the lie.
