From the Document: "The Defense Production Act (DPA) of 1950, as amended (50 U.S.C. 4501 et seq.) is the primary source of presidential authorities to expedite and expand the critical supplies and services from the private sector that are needed to promote national defense. This includes both emergency preparedness and response activities conducted pursuant to title VI of The Robert T. Stafford Disaster Relief and Emergency Assistance Act as well as for the protection and restoration of critical infrastructure operations. The Act requires companies to prioritize government orders and contracts that are necessary to meet the response efforts associated with the coronavirus COVID-19 [coronavirus disease 2019] pandemic. Authorities can also be used to provide financial incentives and assistance to private industry to expand production and capacity for necessary supplies and resources. Four Defense Production Act authorities could be important tools in ongoing efforts to combat the threat of the coronavirus."
