CNN's Jake Tapper asked Democratic Sen. Elizabeth Warren of Massachusetts if she thinks the 2016 Democratic primary was rigged. She said "yes."

This comes after former Democratic National Committee chair Donna Brazile said the DNC was "unethical" and favored Hillary Clinton over Bernie Sanders.



Democratic Sen. Elizabeth Warren of Massachusetts thinks the 2016 Democratic-primary process between Hillary Clinton, the eventual nominee, and Sen. Bernie Sanders of Vermont was rigged, she told CNN's Jake Tapper on Thursday.

Tapper asked Warren about the bombshell claims from former Democratic National Committee chair Donna Brazile that the DNC was "unethical" and favored Clinton over Sanders for the party's nomination. Brazile detailed her "proof" in a book excerpt published by Politico on Thursday.

Brazile wrote that she came across an agreement between the DNC and two Clinton campaign funds that suggested unethical practice, she wrote, adding that the DNC was also required to consult with the campaign about staffing, budgeting, data, analytics, and mailings long before the primary had wrapped up.

"If the fight had been fair, one campaign would not have control of the party before the voters had decided which one they wanted to lead," Brazile added. "This was not a criminal act, but as I saw it, it compromised the party's integrity."

Tapper, in his Thursday interview, asked Warren point-blank if she thought the primary process was rigged.

"Yes," Warren said.

Earlier in the interview, Tapper asked Warren to more broadly address Brazile's claims.

"This is a real problem, but what we've got to do as Democrats now is hold this party accountable," she said. "When Tom Perez was first elected chair of the DNC, the very first conversation I had with him is to say 'you have got to put together a Democratic Party in which everybody can have confidence that the party is working for Democrats rather than Democrats are working for the party.' And he's being tested now."

"This is a test for Tom Perez," she continued. "And either he's going to succeed by bringing Bernie Sanders and Bernie Sanders's representatives into the process, and they're going to say it's fair, it works, we all believe it, or he's going to fail. And I very much hope he succeeds. I hope for Democrats everywhere. I hope for Bernie and all of Bernie's supporters that he's going to succeed.
