John McCain's daughter slams 'cruelty' of Trump supporter who reportedly called for his death

"May God help these people who inflict such cruelty in the world," she tweeted.

Well, that didn't sit well with Meghan McCain, who took to Twitter, writing, "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."

At the rally, Trump did not identify Sen. McCain by name, but he did say -- to the delight of rally-goers -- "One vote away! I will not mention any names. Very presidential, isn't it?"

The previous day, Sen. McCain tweeted a photo of himself and Meghan McCain hiking, writing, "Watching the #SolarEclipse17 with @meghanmccain on a hike in #Arizona!"
