Donna Brazile: Passing potential town hall topics to Clinton camp 'a mistake I will forever regret'

The former interim DNC chair makes the admission in an essay for Time magazine.

She further explains, "My job was to make all our Democratic candidates look good, and I worked closely with both campaigns to make that happen. But sending those emails was a mistake I will forever regret."

Brazile says the media's narrative of the scandal was precisely what Russia was aiming for.

"By stealing all the DNC's emails and then selectively releasing those few, the Russians made it look like I was in the tank for Secretary Clinton," she writes. "Despite the strong, public support I received from top Sanders campaign aides in the wake of those leaks, the media narrative played out just as the Russians had hoped, leaving Sanders supporters understandably angry and sowing division in our ranks."

She continues, "In reality, not only was I not playing favorites, the more competitive and heated the primary got, the harder D.N.C. staff worked to be scrupulously fair and beyond reproach. In all the months the Russians monitored the D.N.C.'s email, they found just a handful of inappropriate emails, with no sign of anyone taking action to disadvantage the Sanders campaign."
