President Donald Trump says he wore a mask in a "back area" during a factory tour in Michigan, but removed it before facing the cameras.
He told reporters he took off the facial covering at the Ford car plant because he "didn't want to give the press the pleasure of seeing it", and he was about to make a speech.
Despite Michigan's attorney general urging the president to comply with health guidelines, the president insisted it was unnecessary because he is regularly tested for coronavirus.
