On July 17, President Donald Trump sat for a Fox News interview at the White House. At the time, nearly 140,000 Americans were dead from the novel coronavirus. The interviewer, Chris Wallace, showed Trump a video clip in which Robert Redfield, the director of the Centers for Disease Control and Prevention, warned of a difficult fall and winter ahead. Trump dismissed the warning. He scoffed that experts had misjudged the virus all along. “Everybody thought this summer it would go away,” said Trump. “They used to say the heat, the heat was good for it and it really knocks it out, remember? So they got that one wrong.”
Trump’s account was completely backward. Redfield and other U.S. public health officials had never promised that heat would knock out the virus. In fact, they had cautioned against that assumption. The person who had held out the false promise of a warm-weather reprieve, again and again, was Trump. And he hadn’t gotten the idea from any of his medical advisers. He had gotten it from Xi Jinping, the president of China, in a phone call in February.
