An executive order is a directive issued by the U.S. president to manage the operations of the federal government. It holds the force of law and is primarily used to implement statutes, direct agencies, or outline policies without needing Congressional approval. The authority for executive orders is derived from the Constitution or specific legislative provisions and is often employed during situations where swift action is necessary. However, executive orders can be contested in court or reversed by future administrations. They play a crucial role in shaping domestic and foreign policy, reflecting the president's agenda and priorities.
