It's a valid concern, based on reports from Italy. The US government has confirmed that the nation has a stockpile of more than 10,000 ventilators, but President Trump also recently told Twitter that it should be the states' responsibility to buy these vital life-saving devices. > Over the past few days, there have been growing calls to mobilize advanced manufacturing industries to meet this need, and on Wednesday night, Elon Musk replied to a fan on twitter that his companies "will make ventilators if there is a shortage."
