Former DNC Chairwoman Debbie Wasserman Schultz resigned after the party’s convention last week as a result of the revelations. DNC Vice Chairwoman Donna Brazile has stepped in as interim chair through the election.

The changes at the DNC come as the Clinton campaign is moving to take greater control of party headquarters in Washington and in states across the country.

Democrats are also trying to get ahead of the disclosure of more emails and internal documents from hacked computer systems, fearful of more embarrassing revelations.

The controversy began late last month when nearly 20,000 internal emails, released by WikiLeaks, were dumped on the Internet.

The emails between a handful of DNC officials revealed conversations about Sanders’ campaign, including one official suggesting he should be questioned about his faith to hurt him in key Southern states.

The emails are believed to have been released by Russian operatives after the DNC was hacked earlier this year. The US has not made an official assessment of responsibility, but has acknowledged that experts agree the hack was committed by hackers working for the Russian military and intelligence.

Though the DNC and Democrats have focused on the implications of suspected Russian meddling in the US election, the emails have cast the organization in a negative light.
