An "executive order" in the context of U.S. law is a directive issued by the President to manage the operations of the federal government. These orders have the force of law and are used to implement policy changes, direct federal agencies, or respond to emergencies. Executive orders often reflect the President's priorities and can significantly influence domestic and foreign policy without needing legislative approval. However, they are subject to judicial review and can be challenged in courts or revoked by subsequent administrations.
