In the United States, an executive order is a directive by the president of the United States that manages operations of the federal government.[1] The legal or constitutional basis for executive orders has multiple sources. Article Two of the United States Constitution gives presidents broad executive and enforcement authority to use their discretion to determine how to enforce the law or to otherwise manage the resources and staff of the federal government's executive branch. The ability to make such orders is also based on expressed or implied Acts of Congress that delegate to the president some degree of discretionary power (delegated legislation).[2] The vast majority of executive orders are proposed by federal agencies before being issued by the president.
