"My father, United States Senator John Sidney McCain III, departed this life today," Meghan began. "I 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. He loved me, and I loved him," she wrote. "He taught me how to live. His love and his care, ever present, always unfailing, took me from a girl to a woman -- and he showed me what it is to be a man."
"All that I am is thanks to him. Now that he is gone, the task of my lifetime is to live up to his example, his expectations, and his love," Meghan continued.
Meghan's mom, Cindy McCain, also remembered her husband on Twitter. The family announced on Friday that McCain had decided to discontinue medical treatment. He was diagnosed with a malignant brain tumor, called a glioblastoma, in 2017.
"My heart is broken. I am so lucky to have lived the adventure of loving this incredible man for 38 years," she said. "He passed the way he lived, on his own terms, surrounded by the people he loved, in the the place he loved best."

Former Vice President Joe Biden -- whose son, Beau, died of the same cancer as McCain -- also released a statement, writing, "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."

.@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.
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
John McCain overcame more in his lifetime than most of us can fathom. He was a true patriot, who set an example of integrity and strength for all of us to follow. He will be missed, but his impact will reverberate for generations. RIP pic.twitter.com/qXAEBCBbFw

John McCain was an American hero, a man of decency and honor and a friend of mine. He will be missed not just in the U.S. Senate but by all Americans who respect integrity and independence. Jane and I send our deepest condolences to his family.
John McCain was an American hero, a patriot, and a maverick unafraid to voice his truth. He served our country valiantly, and his contributions to our nation will live forever. Our thoughts and prayers are with his family today and in the sad days ahead. May he Rest In Peace.
So truly saddened by the passing of @SenJohnMcCain. At a time in our country when we desperately need those who use their voice to speak out with honesty and integrity, the loss of his will leave a vacuum. My thoughts and prayers go out to the McCain family.
To the family of maverick hero Senator John McCain, as the tributes cascade in, hopefully knowing how your husband & father was beloved helps ease the pain of his passing. I was honored to know him & you & my family joins me in sending you our love. All hail the victorious dead.
Meghan has openly discussed her father's cancer diagnosis, including on The View. During her first day as co-host in October 2017, she broke down in tears talking about McCain's health. "I can't believe I'm freaking crying already," she said. "When you hear cancer, a nuclear bomb goes off in your life. No matter who you are. I didn't realize how intense and disruptive and scary and hopeless and chaotic you would feel all day long."
"He's such a warm, wonderful man. And I can call him at any time when I’m feeling overwhelmed by cancer. I can’t express to you and to everyone here what his support and his love of him and his family has meant to me," Meghan said of Biden during a recent appearance on The Late Show With Stephen Colbert. "Cancer’s scary, and having someone like him who’s been through so much tragedy to empathize and give his time, especially because he’s one of the most powerful people on the planet.”
Meghan added of her father: "He is so resilient in so many different ways,” she added. “He’s a tough bastard."
