The 36-year-old conservative began bashing Katie over her admission to having felt threatened by Ashleigh Barnfield, who the former Today show host referred to in her book as "someone younger and cuter around the corner."
"Katie Couric admitted to ostensibly derailing her career because she was threatened by, in her words 'someone younger and cuter around the corner,'" she wrote. "Even if this is something she felt and acted on, writing about it in such a way in her memoir is bizarre. It actually hurts my heart to think of the place Ashleigh Banfield could be at on network television today if it weren't for Katie Couric."
McCain also brought up the incident where Katie admitted to editing her interview with Ruth Bader Ginsburg to make the liberals look good. The progressive icon allegedly said she did not like "those who kneel before rather than salute our American flag," which was cut out of the aired interview.
"And if we now know for a fact that if Katie Couric edited her interviews to make famous liberals look good, one can only imagine and speculate about what she might possibly have done to make conservatives look bad," she wrote.
The Arizona native did confess she has not liked Couric since she interviewed the former Alaska governor Sarah Palin, who was running as VP with her father John in 2008.
"I have an admission. I don't like Katie Couric, I haven't liked Katie Couric since she interviewed Sarah Palin," she shared. "I know the backstory and lived in real time the process of what has now become one of the more notorious trainwreck interviews in political history. Did Sarah Palin perform her best? Of course not."
"But she was being interviewed by an infamous mean girl who has now admitted to leaving out a 'damaging' part of an interview with Ruth Bader Ginsburg where the former Supreme Court justice and left-wing icon admits to not liking those who kneel before rather than salute our American flag," Meghan said.
As Radar previously reported, Meghan had parted ways with the famous talk show The View in July this year, where she worked for four seasons. An insider revealed she has "had enough" after constantly getting into arguments with the other co-hosts as she was the only conservative voice on the panel.
