“Students use a veto message and vetoed bill to make a direct connection between the Constitution, the legislative and veto process, and the separation of powers between the legislative and executive branches of government.” The featured documents (Attempted Override of President Richard Nixon’s Veto of S. 518, an Act to Abolish the Offices of the Director and Deputy Director of the Office of Management and Budget, 1973) enable students to gain a greater understanding of the veto process by working with the Constitution’s veto clauses.
