The Senate passed the amendment, 42 to 35, on April 19, 1898, and the House concurred on the same day. President McKinley signed the joint resolution on April 20th, and an ultimatum was sent to Spain.
Interestingly, I lived in Colorado for a few years and was given the false impression that sugar beet farming arose there following the Cuban embargo that began in 1962. Living in Fort Collins, I would pedal my bicycle past miles of fields planted in sugar beets. Most were owned by farmers of Japanese descent who had been displaced during World War II. They remained in Colorado following the war rather than return to their homes and fight to regain them. However, it was in fact the opening of trade with Cuba that American farmers feared. It was not the end of trade that drove them to grow sugar beets.
