<span>The son of Japanese immigrants, Daniel Ken Inouye volunteered for the U.S. Army after the Pearl Harbor attack in 1941 and joined the famed Japanese-American 442nd Regimental Combat Team. He lost his right arm in a firefight with Germans in Italy in 1945, and would win the Distinguished Service Cross--and belatedly, the Medal of Honor--for his war service. Elected to the House of Representatives as a Democrat in 1959, the year Hawaii became a state, Inouye entered the Senate in 1963. Over his long career, he was a steadfast voice for his state in Washington and drew national attention for his quiet but courageous leadership on high-profile Senate committees investigating the Watergate scandal and the Iran-Contra affair. At the time of his death, Inouye was the longest-serving current U.S. senator, having been elected to nine consecutive terms over 49 years.
