WASHINGTON (Sputnik) — Marshall served as DNC chief financial officer (CFO), Miranda was the communications director while Dacey served the committee’s chief executive officer.
"As the DNC moves into the general election phase of the 2016 campaign, new Chair Donna Brazile today announced the departures of Amy Dacey, Luis Miranda, and Brad Marshall," the statement noted.
Their resignations come as the DNC deals with fallout from an email hacking scandal.
In July, WikiLeaks published almost 20,000 pages of hacked emails that revealed top DNC officials deliberately worked to obstruct Bernie Sanders' presidential campaign in order to boost Hillary Clinton's chances of becoming the party's nominee.
Clinton's campaign has blamed Russia for the cyberattack, but the Kremlin has called this allegation absurd.
