HONOLULU — Senator Daniel Inouye was remembered Sunday as an American hero whose legacy as a war veteran and longtime Democratic senator would be felt across Hawaii for years to come.

The memorial service at Honolulu’s National Memorial Cemetery of the Pacific was attended by more than 1,000 people, including President Obama; the Senate majority leader, Harry Reid; Hawaii’s congressional delegation; and a number of other senators, cabinet secretaries, and other dignitaries.
