WASHINGTON - Sen. Daniel Inouye of Hawaii, the influential Democrat who broke racial barriers on Capitol Hill and played key roles in congressional investigations of the Watergate and Iran-Contra scandals, died Monday. He was 88.
Inouye, a senator since January 1963, was currently the longest serving senator and was president pro tempore of the Senate, third in the line presidential succession. His office said Monday that he died of respiratory complications at a Washington-area hospital.
Senate Majority Leader Harry Reid announced Inouye's death on the Senate floor.
Inouye was a World War II hero and Medal of Honor winner who lost an arm to a German hand grenade during a battle in Italy. He became the first Japanese-American to serve in Congress, when he was elected to the House in 1959, the year Hawaii became a state. He won election to the Senate three years later and served there longer than anyone in American history except Robert Byrd of West Virginia, who died in 2010 after 51 years in the Senate.
After Byrd's death, Inouye became president pro tem of the Senate, a largely ceremonial post that also placed him in the line of succession to the presidency, after the vice president and the speaker of the House.
Although tremendously popular in his home state, Inouye actively avoided the national spotlight until he was thrust into it. He was the keynote speaker at the 1968 Democratic National Convention, and later reluctantly joined the Senate's select committee on the Watergate scandal. The panel's investigation led to the resignation of President Richard Nixon.
Inouye also served as chairman of the committee that investigated the Iran-Contra arms and money affair, which rocked Ronald Reagan's presidency.
A quiet but powerful lawmaker, Inouye ran for Senate majority leader several times without success. He gained power as a member of the Senate Appropriations Committee and chairman of the defense appropriations subcommittee before Republicans took control of the Senate in 1994.
When the Democrats regained control in the 2006 elections, Inouye became chairman of the Senate Commerce Committee. He left that post two years later to become chairman of the powerful Senate Appropriations Committee.
Inouye also chaired the Senate Indian Affairs Committee for many years. He was made an honorary member of the Navajo nation and given the name "The Leader Who Has Returned With a Plan."
In 2000, Inouye was one of 22 Asian-American World War II veterans who belatedly received the nation's top honor for bravery on the battlefield, the Medal of Honor. The junior senator from Hawaii at the time, Daniel Akaka, had worked for years to get officials to review records to determine if some soldiers had been denied the honor because of racial bias.
Inouye's first political campaign in 1954 helped break the Republican Party's political domination of Hawaii. He was elected to the Territorial House of Representatives, where he served as majority leader. He became a territorial senator in 1958.
Inouye was serving as Hawaii's first congressman in 1962, when he ran for the Senate and won 70 percent of the vote against Republican Benjamin Dillingham II, a member of a prominent Hawaii family.
In 1968, President Lyndon Johnson urged Vice President Hubert Humphrey, who had won the Democratic nomination for president, to select Inouye as his running mate. Johnson told Humphrey that Inouye's World War II injuries would silence Humphrey's critics on the Vietnam War.
"He answers Vietnam with that empty sleeve. He answers your problems with (Republican presidential candidate Richard) Nixon with that empty sleeve," Johnson said.
But Inouye was not interested.
"He was content in his position as a U.S. senator representing Hawaii," Jennifer Sabas, Inouye's Hawaii chief of staff, said in 2008.
Inouye reluctantly joined the Watergate proceedings at the strong urging of Senate Democratic leader Mike Mansfield. The panel's investigation of the role of the Nixon White House in covering up a burglary at Democratic National Committee headquarters at the Watergate in June 1972 ultimately prompted the House to initiate impeachment proceedings against Nixon, who resigned before the issue reached a vote in the House.
