Article II, Section 3 commands the President "shall take Care that the Laws be faithfully executed," creating both a source of executive power and a constraint on presidential discretion. These ten words implicate at least five categories of executive authority: powers the Constitution grants directly to the President, powers Congress confers through legislation, powers delegated to department heads and agencies, authority to enforce criminal statutes, and the duty to carry out ministerial functions.
The clause notably says the President shall ensure laws are executed "by others," not execute them personally, establishing the President as supervisor rather than direct implementer. At the Founding, this provision promised prompt and vigorous law enforcement that was absent under the Articles of Confederation. The clause also serves as a major limitation because it underscores the executive must faithfully execute Congress's laws and cannot disregard them. Three presidents faced impeachment partly for allegedly violating Take Care duties: Andrew Johnson, Bill Clinton, and Donald Trump. Courts use this clause to determine whether presidents exceeded constitutional authority by refusing to enforce statutes or by enforcing laws Congress never authorized.
