“Crooked Hillary bought the DNC & then stole the Democratic Primary from Crazy Bernie!” Trump tweeted on Friday morning.

“Lets go FBI & Justice Dept!” he added, noting that “Pocahontas” ‒ his nickname for Senator Elizabeth Warren (D-Massachusetts) ‒ admitted the Democratic National Committee (DNC) had “rigged the primaries.”

Brazile ‒ or “Donna B.” in Trump’s tweets ‒ took over as interim DNC chair in July 2016, after leaked documents compelled the resignation of Clinton confidante Debbie Wasserman Schultz. Her book, "Hacks: The Inside Story of the Break-ins and Breakdowns that Put Donald Trump in the White House," is due to be published Tuesday, a year and a day after the November 2016 election.

In an excerpt from the book, published by Politico on Thursday, Brazile revealed that Clinton had struck a deal with the DNC that had been bankrupted by President Barack Obama’s 2012 campaign, to “control the party’s finances, strategy, and all the money raised.” The party was basically beholden to Clinton’s campaign long before she became the official nominee, shutting out the grassroots campaign by Senator Bernie Sanders (I-Vermont).

Brazile’s disclosures sparked criticisms of the narrative surrounding the alleged Russian meddling in the election.
