From the Executive Summary: "The Defense Production Act (DPA) ['50 U.S.C. 4501 et seq'] grants the president a broad set of authorities to influence domestic industry in the interest of national defense, which defined broadly, includes preparing for and responding to military conflicts, emergency preparedness activities under the Stafford Act, acts of terrorism or continuity of government operations. President Trump has executed three Executives Orders (EO) and four Presidential Memoranda invoking the DPA in response to the novel coronavirus (COVID-19)."
