Trump supporter shouts 'McCain needs to die!' This is how Meghan McCain shut down the hate.

A Trump supporter shouted that Sen. John McCain (R-Ariz.) needed to "die" during President Donald Trump's speech Tuesday night in the senator's home state of Arizona. The senator's daughter, Meghan McCain, a political commentator for Fox News, wasn't having it.

McCain, 80, who rallied after brain surgery and cancer treatments to return to Congress to vote against the Republican health care bill in July, was the target of comments from the president and outright aggression from one Trump supporter in particular during the rally.

Trump, while addressing the health care bill in his speech, refused to name McCain as a Republican who shut down the health care bill, but said, "One vote away! I will not mention any names.”

While the president seemed to refer to McCain with his jab, an as-yet unidentified man yelled out, "McCain needs to die now!" according to journalist David Catanese.

Meghan McCain's response

Meghan McCain, clearly disturbed by the call for her father's death, tweeted Wednesday: "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."

Meghan also received support from CNN's Jake Tapper, who tweeted, "Meghan, every decent person is rooting for your father and your family. Please ignore the haters."

Meghan, on Twitter, responded, "Thank you Jake. 99% of the time I can't. Every once in a while I still react."

"I get it," Tapper responded. "The lack of humanity is astounding. But there are so many more of us feeling the exact opposite for the McCains."

Trump's history with McCain

Trump has a spotty-at-best history with John McCain, whom he blasted in 2015 for being captured and held as a prisoner during the Vietnam War.

Speaking during the Family Leadership Summit in Ames, Iowa, Trump said, "He’s not a war hero," referring to McCain. "He was a war hero because he was captured. I like people who weren’t captured."

Trump almost immediately charted a new course after the outcry at his comments about McCain's war hero status, and he later clarified his statement.

Shifting his position, Trump said, "If somebody’s a prisoner, I consider them a war hero."

During the 2016 presidential race, John McCain spoke out against the infamous Access Hollywood tape that caught Trump speaking ill of women and his treatment of them.

About the tape, McCain said, "I have wanted to support the candidate our party nominated. But Donald Trump's behavior this week, concluding with the disclosure of his demeaning comments about women and his boasts about sexual assaults, make it impossible to continue to offer even conditional support for his candidacy."

Since Trump's election, McCain has been vocal whenever he disagrees with the president. Recently, he specifically called out Trump over his "unclear" proposed transgender military ban.
