Brazile, a former CNN contributor, recalled in her new book when emails stolen from Clinton campaign chairman John Podesta showed that she relayed information about possible topics that would be brought up during the Democratic primary debate hosted by her network.
"The next day, even Jake Tapper took a swing at me, calling me unethical and 'journalistically horrifying' during a radio interview with WMAL even though I worked for CNN as a commentator not a journalist," Brazile wrote in her book Hacks: The Insider Story of the Break-ins and Breakdowns That Put Donald Trump in the White House. "When I called him on this, he did not apologize. His attack on me was really about him. He wrote in an email, 'I don't know what happened here except it undermines the integrity of my work and CNN ... you have to know how betrayed we all feel.'"
Brazile continued, "The feeling is mutual, my friend."
Reached Tuesday by the Washington Examiner, a spokeswoman for CNN said the network had nothing else to add to the controversy.
In an essay for Time magazine in March, Brazile said that "sending those emails was a mistake I will forever regret," though in her book she suggests that she actually may have never sent them, using the word "allegedly" to describe the messages attributed to her. She says in the book she was never able to find the specific emails related to the debate topics in any of her email accounts.
CNN cut ties with Brazile in October of 2016, saying that it was "completely uncomfortable" after learning earlier in the year that she provided Clinton's campaign with specific questions she would face at the network's presidential forums.
Hacks published Tuesday and recounts Brazile's experience working in the Democratic Party to elect Clinton and their loss to Donald Trump.
