Bernie Sanders is facing mounting pressure from his supporters to disavow his endorsement of Hillary Clinton after a WikiLeaks release of 20,000 internal e-mails of the Democratic National Committee indicates the primary election was rigged.

Bernie’s campaign manager, Jeff Weaver, said someone must be held accountable for cheating voters out of a fair and impartial election.

“Someone has to be held accountable,” Weaver told ABC News. “The DNC, by its charter, is required to be neutral among the candidates. Clearly it was not.

“We spent 48 hours of public attention worrying about who in the Donald Trump campaign was going to be held responsible for the fact that some lines of Mrs. Obama’s speech were taken by Melania Trump.”

The WikiLeaks release of 20,000 internal DNC e-mails shows DNC chair Debbie Wasserman Schultz routinely harangued “journalists” like CNN anchor Jake Tapper and MSNBC’s Chuck Todd to provide questions ahead of interviews and to ensure that news coverage of Democrats was positive.

Tapper and Todd often tried to placate the ill-tempered Wasserman Schultz.

Another e-mail shows DNC chief financial officer Brad Marshall suggested that staffers orchestrate a media campaign to paint Bernie Sanders (who is Jewish) as an atheist in order to turn religious voters in Kentucky and West Virginia against him:

“It might may no difference, but for KY and WVA can we get someone to ask his belief. Does he believe in a God. He had skated on saying he has a Jewish heritage.

“I think I read he is an atheist. This could make several points difference with my peeps. My Southern Baptist peeps would draw a big difference between a Jew and an atheist.”

“Wondering if there’s a good Bernie narrative for a story, which is that Bernie never ever had his act together, that his campaign was a mess.”

The Clinton campaign blamed Russians hackers for hacking into the DNC database in order “to help Donald Trump,” without any evidence to support their accusations.

Meanwhile, Hillary has repeatedly claimed the personal e-mail account she used during her four years as Secretary of State which she operated from an unsecured secret server in her basement was never hacked by enemies of the United States, despite evidence suggesting otherwise.

Bernie Sanders spoke at the Democratic National Convention and supported Hillary, but his followers say he must disavow.

For months, the Sanders campaign and his supporters had accused the DNC of having its “finger on the scale” to rig the election in Clinton’s favor.

Wasserman Schultz laughed off the suggestions, calling them silly conspiracy theories.

Debbie Wasserman Schultz was the co-chair of Hillary Clinton’s 2008 presidential campaign. She resigned as DNC chair July 24 after fighting desperately to keep her post.

Just hours after her resignation, Debbie was re-hired by Hillary Clinton as honorary co-chair of her 50-state presidential campaign.

“I want to thank my longtime friend Debbie Wasserman Schultz for her leadership of the Democratic National Committee over the past five years,” Clinton gushed in a statement. “I look forward to campaigning with Debbie in Florida and helping her in her re-election bid.”

Longtime Hillary ally Donna Brazile will be interim DNC chair through the November election.
