Updated at 5:10 a.m. ETHillary Clinton's campaign gained significant control over the Democratic National Committee's finances and strategy more than a year before the election in exchange for helping the party retire lingering debt from the 2012 presidential campaign, according to a new book by a former party chairwoman.The disclosure comes from an excerpt of Hacks: The Inside Story of the Break-ins and Breakdowns That Put Donald Trump in the White House, published in Politico magazine, by Donna Brazile, who took over as party chairperson in July 2016 in the wake of hacked emails showing that many DNC staffers were openly rooting for Clinton in the primary. Brazile says that when she took over as interim chair, she set about trying to untangle the financial web that had grown up around the campaign.She says what she learned was that the DNC had made a deal with Clinton's people in August 2015 to clear up the party's debts."This was not a criminal act, but as I saw it, it compromised the party's integrity," Brazile writes in the book due out next week.Brazile, a former campaign manager for Al Gore and adviser to President Bill Clinton, stepped in as interim head of the DNC after Rep. Debbie Wasserman Schultz, D-Fla., was forced out over the email controversy on the eve of the party's convention."As Hillary's campaign gained momentum, she resolved the party's debt and put it on a starvation diet. It had become dependent on her campaign for survival, for which she expected to wield control of its operations," Brazile writes.In a phone call she placed to Gary Gensler, the chief financial officer of Clinton's campaign, just after the party's convention in July, "He described the party as fully under the control of Hillary's campaign, which seemed to confirm the suspicions of the [Vermont Sen.] Bernie [Sanders] camp. The campaign had the DNC on life support, giving it money every month to meet its basic expenses, while the campaign was using the party as a fund-raising clearinghouse," she adds.The Washington Post writes:
