President Donald Trump today ordered General Motors to make ventilators to treat COVID-19 patients and accused the company of "wasting time." Trump announced that he "signed a Presidential Memorandum directing the Secretary of Health and Human Services to use any and all authority available under the Defense Production Act to require General Motors to accept, perform, and prioritize Federal contracts for ventilators."

Hours before Trump took this step, GM said it is working with ventilator-maker Ventec Life Systems "to deliver the first ventilators next month and ramp up to a manufacturing capacity of more than 10,000 critical care ventilators per month with the infrastructure and capability to scale further."
