COLUMBUS (AP) — Ohio’s governor has ordered all flags at public buildings and grounds in the state be flown at half-staff to honor the life and service of Arizona Republican Sen. John McCain.

Gov. John Kasich on Sunday evening ordered the flags lowered effective immediately through the day of McCain’s interment. The six-term senator, Vietnam War hero and prisoner of war died Saturday at his Arizona ranch after a yearlong battle with brain cancer. The date for his burial hasn’t been released.

McCain’s office website has said he will lie in state and have funeral services in Arizona and Washington. A private funeral and burial is planned at the U.S. Naval Academy in Annapolis, Maryland.

In a statement Saturday, Kasich described McCain as “an iconic American hero, patriot and statesman without compare.”

U.S. Senator Rob Portman (R-Ohio) issued the following statement in response to the news that Senator McCain died at the age of 81: “John McCain was a true patriot who lived the motto of his 2008 campaign: Country First. Always. He was also a friend and someone I looked to for counsel. In the Senate, we relied on his expertise on national security issues, were inspired by his life’s story, and charmed by his sense of humor. He was a lion of the Senate, and the place will not be the same place without him.

“Jane’s and my prayers are with Cindy and the entire McCain family during this difficult time,” Portman added

Sen. Sherrod Brown (D-Ohio) said, “We all mourn the loss of a national treasure and a national hero, and a friend to so many of us, John McCain. I had a glimpse of John’s character on Jan. 21, 2009 when he rode a bus with a number of us in the Senate to the National Prayer Breakfast, a day honoring the inauguration of new President Barack Obama. It was only two months after a disappointing loss, of course, in a hard-fought campaign, but we all would have understood if Sen. McCain did not want to join us on that bus and go to the prayer breakfast. But as always he did his duty; he put his country first.

“That was John McCain,” Brown added.
