At the direction of the President of the United States, Gov. David Ige has ordered that the United States flag and the Hawai‘i state flag will be flown at half-staff on Monday, Sept. 11, 2017 at the State Capitol and upon all state offices and agencies as well as the Hawai‘i National Guard in the State of Hawai‘i. The flags will be flown at half-staff until sunset.
This action will mark Patriot Day, in honor of the nearly 3,000 people who died in the terrorist attacks on Sept. 11, 2001, and those who so nobly aided their fellow citizens in America’s time of need.
The president also proclaims Friday, Sept. 8 through Sunday, Sept. 10, 2017 as National Days of Prayer and Remembrance in honor of those lost 16 years ago, as well as their grieving families and the brave first responders who acted with such heroism.
