In all my years, I have never seen anything quite like this: a U.S. president who lies and demonizes at the drop of a hat. I don’t just mean President Trump makes statements that tend to be inaccurate or misleading or that he exaggerates, equivocates and, at times, shades the truth.

No, this president repeatedly makes declarations that are flat-out at variance with established facts; assertions that on their face cannot be true.

As The Post’s “Fact Checker” column noted this week, until Wednesday, when Trump signed an executive order ending the separation of migrant families at the Mexican border, his “administration was insisting that it didn’t have a policy of separating families (false), that several laws and court rulings were forcing these separations (false), that Democrats were to blame (false), that only Congress could stop family separations (false) and that an executive order wouldn’t get the job done.”

No other words for it: Trump is a baldfaced liar.
