Former Democratic National Committee Chairwoman Donna Brazile said she felt betrayed by CNN anchor Jake Tapper in the controversy over her decision to share Democratic debate questions with Hillary Clinton last year, an act she has since admitted.

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.
