This bill restricts various presidential and federal authorities related to the acquisition of supplies to combat COVID-19. Specifically, the bill prohibits the President from exercising certain authorities under the Defense Production Act of 1950 to prioritize the performance of federal contracts or orders for COVID-19 supplies over the performance of state or territorial contracts or orders. In addition, states or territories may use federal COVID-19 relief funds for COVID-19 supplies that they had been unable to purchase because of prioritized performance of federal contracts or orders. (The Defense Production Act of 1950 confers upon the President a broad set of authorities to influence domestic industry in order to provide essential materials and goods needed for the national defense.) Additionally, the Food and Drug Administration may not ration, limit, restrict access to, or otherwise control the quantity of a medical product authorized for use during an emergency, including by requiring products to be distributed through a state- or territorial-based system.
