John McCain was many things – a proud graduate of the Naval Academy, a Senate colleague, a political opponent.

But, to me, more than anything, John was a friend. He will be missed dearly. pic.twitter.com/AS8YsMLw3d

John McCain believed that every citizen has a responsibility to make something of the freedoms given by our Constitution, and from his heroic service in the Navy to his 35 years in Congress, he lived by his creed every day. https://t.co/946T7PnG53

I count it as a blessing to have had the honor to serve with John McCain in the Senate and on the Armed Services Committee. If there ever was a true American patriot, John was that patriot. I’ll miss his strength and his maverick spirit, but most of all I’ll miss his kindness. pic.twitter.com/UzYvlRN1No

In honor of John McCain, one of our nation's finest public servants — I direct New York State's flags be flown at half staff. A small gesture for one of America's giants. Godspeed, Senator McCain. pic.twitter.com/FThP1KQEc5

John McCain's finest moment (for me) came in 2008, when a woman at a rally referred to Obama as an Arab. "No, ma'am," McCain replied. "He's a decent family man, a citizen that I just happen to have disagreements with." That's manning up.

Senator John McCain stand für ein Amerika, das ein verlässlicher und enger Partner ist, das aus Stärke Verantwortung für andere übernimmt und auch in schwierigen Momenten zu seinen Werten und Prinzipien steht. Wir werden seine Stimme in Erinnerung behalten.

Mit John #McCain verliert Deutschland einen Freund, der die transatlantische Partnerschaft auch in schwierigen Zeiten verteidigt und sich immer mit voller Kraft für eine liberale, westlich geprägte Weltordnung eingesetzt hat. Unsere Gedanken sind bei seiner Familie.

With the passing of John #McCain the American people lose an exceptional politician. Europe loses a friend, who always believed in transatlantic cooperation. He had a clear moral compass and he always aimed at serving his country. My heartfelt condolences are with his family. pic.twitter.com/H1RxR5NKDE
