President Trump did the tour in a Michigan Ford plant this afternoon without a mask.
The policy obliges everyone to wear masks. While Ford told the White House about the policy earlier this week, a company spokesperson added, "The White House has its own safety and testing policies in place and will make its own determination."
A source familiar with the President's visit to a Ford plant said the President wore a mask out of sight of cameras during his visit.
He was just asked why he was not wearing a mask while on the tour in front of the cameras.
"I had one on before in this back area. But I didn’t want to give the press the pleasure of seeing it," Trump said.
Earlier this morning, Michigan Attorney General Dana Nessel said that if Trump "fails to wear a mask, he's going to be asked not to return to any unclosed facilities inside our state."
