A little more than a year after being diagnosed with an aggressive brain tumor, and just one day after his family revealed his decision to stop receiving cancer treatment, Senator John McCain has died at the age of 81. A lauded Vietnam War veteran (as a Navy pilot, he spent five years as a POW) and a six-term senator who went head-to-hear with Barack Obama during the 2008 presidential election, McCain passed away on Saturday, August 25, in his native Arizona.

Tributes poured in after his death. Hillary Clinton took to Twitter, writing, 鈥淗e was a tough politician, a trusted colleague, and there will simply never be another like him.鈥 Meanwhile, Obama proclaimed, 鈥淔ew of us have been tested the way John once was, or required to show the kind of courage that he did.鈥

No tribute was as moving, however, as the one that came from his daughter, Meghan McCain.

The 33-year-old co-host of The View penned a heartbreaking note to her dad. 鈥淚 was with my father at his end as he was with me at my beginning. In the thirty-three years we shared together, he raised me, taught me, corrected me, comforted me, encouraged me, and supported me in all things,鈥 she began. 鈥淗e loved me, and I loved him. He taught me how to live. His love and his care, ever present, always unfailing, took me from a girl to a woman 鈥 and he showed me what it is to be a man.鈥

鈥淎ll that I am is thanks to him,鈥 she continued. 鈥淣ow that he is gone, the task of my lifetime is to live up to his example, his expectations, and his love. 鈥 He was a great fire who burned bright, and we lived in his light and warmth for so very long. We know that his flame lives on, in each of us. The days and years to come will not be the same without my dad 鈥 but they will be good days, filled with live and love, because of the example he lived for us.鈥

Senator McCain鈥檚 wife, Cindy, also shared a moving tribute, writing, 鈥淢y 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.鈥
