President Donald Trump donned a mask for the first time in public Saturday. He was visiting Walter Reed Military Medical Center. It was a carefully staged photo op. He sported a navy blue mask bearing the presidential seal. He had previously refused to wear a mask and wouldn’t ask other Americans to do so, saying it was a personal choice. Critics had said his refusal to wear one showed a lack of leadership. Just before his visit, he told reporters why he’ll wear one Saturday: “I think when you are in a hospital, especially in that particular setting when you are talking to a lot of soldiers, people that in some cases just got off the operating table, I think it’s a great thing to wear a mask.” Trump made the move as new coronavirus cases keep hitting record highs.
