WASHINGTON (AFP) - Democrat Daniel Inouye, one of the last World War II heroes in Congress and the longest-serving member of the US Senate, having represented Hawaii since the state joined the union, died Monday at age 88. The veteran lawmaker, who voted on some of the most historic US legislation of the last half century including the Civil Rights Act of 1964, died of respiratory problems after spending recent weeks in hospital, his office said. His last word was “Aloha,” Inouye’s office said in a statement shortly after Senator Harry Reid announced the death on the Senate floor.
