His family thanked everyone for their continued support.
Sen. John McCain’s family announced Friday that he will no longer undergo treatment for his brain cancer.
"The progress of disease and the inexorable advance of age render their verdict. With his usual strength of will, he has now chosen to discontinue medical treatment," the family said in a statement.
The 81-year-old was diagnosed with an aggressive glioblastoma last summer.
McCain’s wife and daughter took to Twitter to offer their own words of encouragement.
Cindy McCain, his wife, wrote, "I love my husband with all of my heart. God bless everyone who has cared for my husband along this journey."
His daughter, Meghan McCain, thanked people for their continued support.
“We could not have made it this far without you — you've given us strength to carry on,” she said.
