An executive order is a directive issued by the President of the United States to manage the operations of the federal government. These orders have the force of law and enable the President to implement policies, enforce existing laws, or exercise authority as outlined in legislation. Executive orders can address a wide array of issues, from administrative matters to national security and environmental regulations. However, they may face legal challenges or pushback from Congress, highlighting the complex balance of power between branches of government under the U.S. Constitution.
