"What a liar" — famously muttered into an open mike.

It's the one thing I've always remembered about Daniel K. Inouye.

Dead now, at age 88.

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....

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.
