 rare case in which a criminal investigation of the
President&#x2019;s conduct is justified, inquiries to determine whether the President
acted for a corrupt motive should not impermissibly chill his performance of his
constitutionally assigned duties. The conclusion that Congress may apply the obstruction
laws to the President&#x2019;s corrupt exercise of the powers of office accords with our
constitutional system of checks and balances and the principle that no person is above the
law.
