Senate Roll Call for the attempted override of President Buchanan's veto of S. 416, June 23, 1860
The 36th Congress (1859–1861) tried to pass the Homestead Act over President James Buchanan’s veto. To override a presidential veto, the Constitution requires a two-thirds majority in each house of Congress. The Senate could not garner enough support for an override.
