The latest release is the second in the last few days. The
release of 20,000 emails just before the opening of the Democratic
convention prompted the organization's chairwoman, Debbie Wasserman
Schultz, to step down.
WikiLeaks, a group that publishes original documents from
anonymous sources and leakers, released the data without indicating its
source. The emails were sent during a 17-month period between January
2015 and May of this year. The DNC announced in June that its systems
had been hacked.
Democratic officials said at that time that hackers based in
Russia were responsible for the intrusion.
The party organization has not commented on the emails released
by WikiLeaks, but neither has it disputed their authenticity.
The manager of Sanders' political campaign, Jeff Weaver, said the
emails confirmed "what many of us have known for some time," that DNC
members were "actively helping the Clinton effort and trying to hurt
Bernie Sanders' campaign.''
