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.— Cindy McCain (@cindymccain) August 26, 2018
