How to Deal With the Lies of Donald Trump

The acute version is the emergence as president-elect of a man whose nature as a liar is outside what our institutions are designed to deal with. Donald Trump either cannot tell the difference between truth and lies, or he knows the difference but does not care. Tiniest example: On a single day during the campaign, Trump claimed that the National Football League had sent him a letter complaining that the presidential-debate schedule conflicted with NFL games (which the NFL immediately denied), and then he said the Koch brothers had begged him to accept their donations (which they also flat-out denied).

Most people would hesitate before telling easily disprovable lies like these, much as shoplifters would hesitate if the store owner is looking at them. Most people are fazed if caught in an outright lie. But in these cases and others, Trump never blinked. As part of his indispensable campaign coverage this summer, David Fahrenthold (and Robert O’Harrow) of The Washington Post offered astonishing documentation of Trump being caught in a long string of business-related lies and simply not caring.
