Donna Brazile, the former interim chairwoman of the Democratic National Committee, responded to pushback against her forthcoming book about the Democratic Party, telling her critics to "go to hell."

"For those who are telling me to shut up — they told Hillary [Clinton] that a couple of months ago — you know what I tell them? 'Go to hell.' I'm going to tell my story," Brazile said on ABC "This Week" on Sunday.

"Because this is a story of a young girl who started in American politics at the age of 9, who continues to fight each and every week of her life," she added.

In an excerpt of her book, published this week in Politico, Brazile writes of a fundraising deal that she says allowed Clinton's campaign to influence the party's finances before Clinton won the nomination. It also left the door open for other candidates to make similar arrangements.

Brazile wrote that she was stunned to find out about the agreement. She said the agreement was a "cancer" on the party and claimed that it led the DNC to treat Sen. Bernie Sanders, I-Vt., unfairly during the primaries.

The Sanders campaign later signed its own joint fundraising agreement with the DNC but did not use it.

Brazile added Sunday that she found no evidence that the party's primaries were "rigged" against Sanders.

Clinton won 16.8 million votes to Sanders' 13.2 million in the primaries.

Brazile writes in her book that she considered replacing Clinton as the party's presidential nominee after Clinton appeared unsteady and stumbled during last year's Sept. 11 memorial service in New York City.

She wrote that she considered several possible alternatives and decided that Vice President Joe Biden and Sen. Cory Booker, D-N.J., would be the strongest combination to beat Donald Trump in November.

Former Clinton campaign officials said in an open letter Saturday that they were stunned that Brazile considered a replacement.

"We were shocked to learn the news that Donna Brazile actively considered overturning the will of the Democratic voters by attempting to replace Hillary Clinton and Tim Kaine as the Democratic Presidential and Vice Presidential nominees," they said in the statement. "It is particularly troubling and puzzling that she would seemingly buy into false Russian-fueled propaganda, spread by both the Russians and our opponent, about our candidate's health."

Current DNC Chairman Tom Perez on Sunday's "Meet The Press" called Brazile's claims "ludicrous."
