In U.S. governance, an executive order allows the President to issue directives that have the force of law without congressional approval. This tool is often employed to implement policy changes quickly or to address urgent issues. Executive orders can influence a wide range of matters, from national security to environmental regulations. However, they may be met with political opposition, and subsequent administrations can overturn or modify earlier orders. The use of executive orders illustrates the balance of power and the dynamic nature of the executive branch in shaping policy.
