Hair splitting vs fact checking

For all the complaints about Trump seeming impervious to all fact-checking, it doesn’t help very much when fact-checkers at major newspapers of record solemnly announce that Bill Clinton never signed NAFTA on the grounds that George H.W.

Absurd hair-splitting technicality arguments don’t strengthen fact-checking.
