United States Capitol shooting

On March 1, 1954, four Puerto Rican nationalists, seeking to promote Puerto Rican independence from the United States, attacked the United States Capitol. The nationalists, identified as Lolita Lebrón, Rafael Cancel Miranda, Andres Figueroa Cordero, and Irvin Flores Rodríguez, unfurled a Puerto Rican flag and began shooting at Representatives in the 83rd Congress, who were debating an immigration bill. They were captured and imprisoned but their sentences were commuted in the late 1970's by Carter. All four returned to Puerto Rico.
