For two days before President Trump’s visit on Thursday to a Ford factory in Michigan, controversy raged over whether he would — or should — wear a surgical mask while he was there.

Ford had put out the word that masks were mandatory in the Ypsilanti factory — which is making personal protective equipment — though Trump had previously made it clear that, counter to federal recommendations and Michigan law, he didn’t see masks as his kind of thing. So the Michigan attorney general put out a statement imploring the president to comply.
