Funding Restrictions and Separation of Powers

Congress's "power of the purse"-its authority to deny access to public funds-is one of its most essential constitutional authorities. A central mechanism through which English parliaments clawed liberty from reluctant monarchs, it remains a crucial check on executive overreaching. It may provide power to stop a president in his tracks. And yet, two centuries after the founding, the scope of this congressional power and its relationship with constitutional executive authorities remains both contested and inadequately theorized.
