On 11 April 1898, McKinley asked Congress for authority to send U.S. troops to Cuba for the purpose of ending the civil war there. On 19 April, Congress passed joint resolutions (by a vote of 311 to 6 in the House and 42 to 35 in the Senate) supporting Cuban independence and disclaiming any intention to annex Cuba, demanding Spanish withdrawal, and authorizing the president to use as much military force as he thought necessary to help Cuban patriots gain independence from Spain. This was adopted by resolution of Congress and included from Senator Henry Teller the Teller Amendment, which passed unanimously, stipulating that "the island of Cuba is, and by right should be, free and independent". The amendment disclaimed any intention on the part of the United States to exercise jurisdiction or control over Cuba for other than pacification reasons, and confirmed that the armed forces would be removed once the war is over. Senate and Congress passed the amendment on 19 April, McKinley signed the joint resolution on 20 April and the ultimatum was forwarded to Spain. War was declared on 20/21 April 1898.
