President Trump has a well-documented problem telling the truth.

Fact checkers have compiled lists of all of Mr. Trump’s falsehoods since he took office (The Washington Post counts over 7,500, and The Toronto Star over 3,900), rounded up his most egregious whoppers in year-end lists and scrutinized his claims in real time with television chyrons.
