Executive order authority stems from the U.S. Constitution's Article II, granting the President power to manage the federal government and "take Care that the Laws be faithfully executed". It's a tool for directing federal agencies and officials, not a source of new power, meaning orders must derive from existing constitutional or statutory authority, allowing presidents to set policy, prioritize actions, and implement laws, though they can be challenged in court and overturned by subsequent presidents or Congress.
