What If Congress Stops Checking a President?

May 14, 2026

The Constitution’s system of checks and balances depends heavily on Congress.

The Framers did not assume that presidents would voluntarily restrain themselves. Instead, they expected ambition to counter ambition. Congress was therefore given significant constitutional powers designed to prevent excessive concentration of executive authority.

Those powers include control over appropriations, investigative authority, impeachment powers, Senate confirmation authority, and the ability to enact legislation governing executive conduct.

American history contains examples of Congress actively asserting those powers. During Watergate, congressional investigations and hearings played a major role in exposing presidential misconduct and increasing pressure that ultimately led to President Nixon’s resignation. Following the Vietnam War, Congress enacted the War Powers Resolution in an effort to reassert legislative authority over military engagements.

At other times, however, Congress has been less willing to confront presidents — particularly during periods of war, crisis, or intense partisan alignment. In such periods, executive power often expands in practice.

The larger constitutional concern is not simply whether presidents seek more power. Presidents throughout history often have. The deeper question is whether the other branches continue to exercise their own constitutional responsibilities.

The American constitutional system was designed around institutional rivalry and mutual restraint. If Congress ceases to function as an effective counterweight to executive authority, the balance envisioned by the Framers becomes increasingly difficult to maintain.
