Elon Musk tweeted Friday that Tesla and SpaceX employees are “working on ventilators” even though he doesn’t believe they will be needed.

His confirmation on Twitter that both of the companies he leads are working on ventilators comes a day after New York City Mayor Bill de Blasio  made a direct plea to Musk to help alleviate a shortage at hospitals gearing up to combat COVID-19.
