The US has established an airbridge of flights from abroad to bring in supplies of masks, gowns, all the supplies we’re hearing are in short supply. But in answer to a question from Weijia Jiang of CBS News, the Admiral in charge of this effort explained that those supplies mainly are not going to FEMA or the states. They’re going to private sector distributors.
There’s video (I can’t get it to work) of Rear Admiral Polowczyk explaining this in a press conference. According to Heather Cox Williams, his justification for going through the private sector was , “I’m not here to disrupt a [commercial] supply chain.”
