Article II of the Constitution vests “the executive power” in the President. Advocates of presidential power have long claimed that this phrase was originally understood as a term of art for the full suite of powers held by a typical eighteenth- century monarch. In its strongest form, this view yields a powerful presumption of indefeasible presidential authority in the arenas of foreign affairs and national security.
This so-called Vesting Clause Thesis is conventional wisdom among constitutional originalists. But it is also demonstrably wrong. Based on a comprehensive review of Founding-era archives—including records of drafting, legislative, and ratification debates, committee files, private and official correspondence, diaries, newspapers, pamphlets, poetry, and other publications—this Article not only refutes the Vesting Clause Thesis as a statement of the original understanding, but replaces it with a comprehensive affirmative account of the clause that is both historically and theoretically coherent.
