McCain underwent surgery in July 2017 to remove a blood clot in his brain after being diagnosed with an aggressive tumor called a glioblastoma, the same type of tumor that killed Sen. Edward M. Kennedy at age 77 in 2009.
Many politicians and family members took to social media to honor the life and legacy of Senator McCain.
McCain is expected to be honored in Arizona and Washington before being buried, likely this coming week, at the U.S. Naval Academy Cemetery in Annapolis, Maryland. Bush is among those expected to speak at McCain's funeral.
My heart is broken. I am so lucky to have lived the adventure of loving this incredible man for 38 years. He passed the way he lived, on his own terms, surrounded by the people he loved, in the the place he loved best.

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
.@SenJohnMcCain lived a life of service to his country, from his heroism in the Navy to 35 years in Congress. He was a tough politician, a trusted colleague, and there will simply never be another like him. My thoughts and prayers are with Cindy and his entire family.

….And I’ve lost one of my dearest friends and mentor.
I will need some time to absorb this, but I want Cindy —and the entire McCain family — to know they are in my prayers.

"Some lives are so vivid, it is difficult to imagine them ended. Some voices are so vibrant, it is hard to think of them stilled.

Nothing will overcome the loss of Senator McCain, but so that generations remember him I will be introducing a resolution to rename the Russell building after him.
