After the first independence mission, public funding of such missions was ruled illegal. Subsequent independence missions in 1922, 1923, 1930, 1931 1932, and two missions in 1933 were funded by voluntary contributions. Numerous independence bills were submitted to the U.S. Congress, which passed the Hare-Hawes-Cutting Bill on December 30, 1932. U.S. President Herbert Hoover vetoed the bill on January 13, 1933. Congress overrode the veto on January 17, and the Hare–Hawes–Cutting Act became U.S. law. The law promised Philippine independence after 10 years, but reserved several military and naval bases for the United States, as well as imposing tariffs and quotas on Philippine exports. The law also required the Philippine Senate to ratify the law. Manuel L. Quezon urged the Philippine Senate to reject the bill, which it did. Quezon himself led the twelfth independence mission to Washington to secure a better independence act. The result was the Tydings–McDuffie Act of 1934 which was very similar to the Hare-Hawes-Cutting Act except in minor details. The Tydings-McDuffie Act was ratified by the Philippine Senate. The law provided for the granting of Philippine independence by 1946.
