On February 19, 2025, President Trump issued Executive Order 14219, entitled “Ensuring Lawful Governance and Implementing the President’s ‘Department of Government Efficiency’ Deregulatory Initiative.” The Order directs agencies to review all regulations for conformance with the law and the administration's policy. Agencies are required to identify regulations that fall within certain classes defined by the Order, which include “regulations that are based on anything other than the best reading of the underlying statutory authority or prohibition” and “regulations that implicate matters of social, political, or economic significance that are not authorized by clear statutory authority.” The Order also addresses enforcement priorities and requirements for new regulations.
