When Warren was asked by CNN last week if she agrees with the notion that the Democratic National Committee was "rigged" for Clinton, the Democratic senator replied, "yes."
But Brazile told Stephanopoulos she "found no evidence" the primary was "rigged."
"I said I would get to the bottom of everything, and that's what I did," Brazile said. "I called Senator Sanders to say, you know, I wanted to make sure there was no rigging of the process ... I found no evidence, none whatsoever."
What Brazile did find was a memorandum of agreement between the DNC and the Clinton campaign, she said.
Brazile described the relationship between the DNC and the Clinton campaign, with Clinton’s headquarters in Brooklyn controlling the DNC’s spending during the general election.
“I become chair and I'm trying to write a check for something. I raised the money and they're like, you have got to get signed off from Brooklyn. I said Brooklyn?” Brazile said.
“The people who were making the decisions, even for the DNC, they didn't come and work with us,” Brazile added. “They told us to shut up and basically let them win the election, and when we tried to intervene, we had to spend money we raised to try to help them win.”
Brazile also addressed President Trump's responding to reports on her book with a call for the Justice Department to investigate Democrats. "Crooked Hillary bought the DNC and stole the Democratic primary from Crazy Bernie," he tweeted Friday.
Brazile said on "This Week" that Trump “needs to look at his own house before he tries to clean up someone else's.”
“Donald Trump likes to distract,” she said. “What Donald Trump should be focusing on right now is protecting our country from being hacked again. He should be working with Congress to ensure that the American people will feel confident that we are going to have a good election season in 2017, 2018. Donald Trump loves to distract us and divide us. I'm not playing his game.”
Brazile said she received threats as a result of Trump's attacks against her during the campaign.
“I have worked on campaigns all my adult life," she said. "I have been called some of the worst things in America. But when Donald Trump would go out there and attack me, I got the threats [that] were just unbearable. My house right now is -- I got every different kind of security device. I had to get my home swept. I had to get the DNC swept twice. It was horrible.”
