Coulter reinvigorated their feud with a since-deleted Fox News blog post called "Liberals Go Crazy for the Mentally Ill," in which she wrote:
"MSNBC's Martin Bashir suggested that Republican senators need to have a member of their families killed for them to support the Democrats' gun proposals. (Let's start with Meghan McCain!)."
The offending quip refers to Martin Bashir's interview with Rep. Elijah Cummings, D-Md., whose nephew was lethally shot in 2011.
McCain and her mother responded in a series of tweets on Wednesday and Thursday. People like Coulter "only live to spread hate and negativity," McCain said.
Apparently Ann Coulter made a joke about me being killed in a recent column. I should expect nothing less but disgusted regardless.— Meghan McCain (@MeghanMcCain) April 11, 2013
My father is a very famous politician. My family gets a lot of threats. Joking about me being killed really isn't funny or appropriate.— Meghan McCain (@MeghanMcCain) April 11, 2013
Her mother Cindy got into the fray with a few tweets defending her daughter.
"Ann Coulter needs to get a life!" she said. "Ann Coulter have one of your family members threatened. See how you feel!"
