Terming Donna Brazile's interactions with Hillary Clinton's campaign as "unethical," CNN chief Jeff Zucker said the former network commentator's approach was "disgusting," The Huffington Post reported.

Zucker's comment comes in the wake of reports that Brazile informed the Clinton campaign in March about an expected question at a Democratic primary debate against Vermont Sen. Bernie Sanders.

"I have no tolerance for her behavior or that kind of behavior," Zucker added.

Brazile, who also served as vice chair of the Democratic National Committee and became interim DNC chair following the resignation of Rep. Debbie Wasserman Schultz, after emails published by Wikileaks showed party officials supporting Clinton's candidacy even though the organization was not meant to take any stand during the primary, according to The New York Times.

CNN had suspended Brazile's contract for the time being and she was expected to return to the network after the elections. But WikiLeaks published Brazile's email on Oct. 11 in which she appeared to send the Clinton campaign a question ahead of a March town hall event.

On Monday, CNN said it had accepted her formal resignation on Oct. 14.

"We are completely uncomfortable with what we have learned about her interactions with the Clinton campaign while she was a CNN contributor," Lauren Pratapas, a network spokeswoman, said in a statement.



CNN previously clarified that the network had not given Brazile any questions and said there could be a possibility that TV One host Roland Martin, who co-moderated the March debate with CNN's Jake Tapper, or someone close to Martin provided the question in advance to Brazile.

Another possibility which cannot be ruled out is Brazile may have got a hint of the question after she met a woman at a CNN volunteer event in Flint, Michigan, just before the debate.

In a March 5 email to the Clinton campaign, Brazile mentioned that "a woman with a rash" would be asking Clinton a question the next night.
