Mike answered correctly. Trump declared a public health emergency under the Public Health Service Act on Jan. 31, issued two national emergency declarations under both the Stafford Act and the National Emergencies Act (NEA) on March 13, and invoked emergency powers via Executive Order under the Defense Production Act on March 18. On March 19, Trump named the Federal Emergency Management Agency (FEMA) as the lead agency in the COVID-19 emergency response efforts, a designation previously held by the Department of Health and Human Services (HHS). https://www.ncsl.org/ncsl-in-dc/publications-and-resources/president-trump-declares-state-of-emergency-for-covid-19.aspx
