Donald Trump has doubled down on his claim that hospitals are exaggerating the need for medical supplies—specifically face masks. 

"How do you go from 10 to 20 to 30,000, to 300,000 — even though this is different," he told reporters Sunday, during a coronavirus press briefing. "Something is going on. And you ought to look into it as reporters. Where are the masks going? Are they going out the back door."
