Here's What Meghan McCain Wrote To A Trump Supporter Who Said Her Father Should Die

President Trump's campaign-style rally at the Phoenix Convention Center on Thursday drew thousands of protesters demonstrating against the administration. From the rally that night, US News reporter David Cantonese tweeted a video of a supposed Trump supporter shouting at protestors, "McCain needs to die now," referencing the Arizona senator's struggle with brain cancer. The video caught the attention of his daughter, Meghan McCain, who criticized the man at Trump's Phoenix rally who called for her father's death.

"I wouldn't wish seeing this about your own father on my worst enemy. May God help these people who inflict such cruelty in the world," McCain wrote on Twitter on Tuesday night. The 32-year-old quickly received supportive responses to her tweet about her father.

"Meghan, every decent person is rooting for your father and your family. Please ignore the haters," Jake Tapper, CNN's top correspondent, wrote on Twitter.

"Just try to feel sorry for these people. The darkness they live in must be hell. Some day they'll know it as hell and it will be too late," wrote Twitter user Toni Cosentino Hayes.

The subject of her father's death is particularly sensitive since the Arizona Sen. was diagnosed with glioblastoma multiforme, a rare form of brain cancer that rarely occurs in adults.

The diagnosis was officially made, and shared with the public, in July after McCain had a surgery to remove a blood clot above his eye. Following the surgery, the Senator's office shared the brain cancer diagnosis with the public in a statement, quickly receiving an outpouring of support.

"Senator McCain appreciates the outpouring of support he has received over the last few days. He is in good spirits as he continues to recover at home with his family in Arizona. He is grateful to the doctors and staff at Mayo Clinic for their outstanding care, and is confident that any future treatment will be effective. Further consultations with Senator McCain's Mayo Clinic care team will indicate when he will return to the United States Senate," the office wrote in a follow-up statement.

According to the American Brain Tumor Association, there are only about 12,390 new cases a year in the U.S.

When she first found out about her father's diagnosis, McCain shared her love for him on Twitter. "The news of my father's illness has affected every one of us in the McCain Family," she wrote. "It won't surprise you to learn that in all this, the one of us who is most confident and calm is my father."
