Sen. Bernie Sanders Bernie SandersOutrage erupts over Breonna Taylor grand jury ruling Dimon: Wealth tax 'almost impossible to do' Grand jury charges no officers in Breonna Taylor death MORE's (I-Vt.) campaign manager said it would take the Democratic National Committee (DNC) to federal court Friday afternoon if it does not lift the suspension to the campaign's voter database.

The DNC suspended its access to the party's voter database, which includes the Sanders campaign's own data, after revelations that a campaign staffer obtained private data from rival Democratic candidate Hillary Clinton's presidential campaign.

Weaver told reporters that the campaign alerted the DNC about this problem two months ago, when it believed that some of its data had been "lost to one of the other campaigns."

In an interview with CNN's "Wolf" immediately after the Sanders campaign's press conference, DNC Chairwoman Debbie Wasserman Schultz denied that Sanders's voter information had been compromised two months ago, as Weaver claimed.

"We are following the agreement that both parties entered into. ... I'm confident that this is the decision that they would expect from us and it’s the same decision that we would make if the shoe was on the other foot." She said the party's investigation found that the Sanders campaign "not only viewed it, but they exported it and downloaded it." She brushed off the threat of legal action. "The Sanders campaign doesn’t have anything other than bluster to put out there," she said on CNN.

News of the suspension comes the day after Sanders landed endorsements from the Communications Workers of America union and from the progressive Democracy for America (DFA). It also comes just a day before the third Democratic debate, which Sanders's spokesman Michael Briggs slammed on Friday for being scheduled for a time when interest is likely to be low.

By suspending the Sanders campaign from access to its own database, the DNC was "actively attempting to undermine our campaign," Weaver said, accusing the party of tilting the scales for the Clinton campaign.

"C learly in this case it looks like they are trying to help the Clinton campaign," he said.

“I don’t know the motivation of every single person at the DNC, but you look at the pattern of conduct,” Weaver continued. “We’ve obviously had concerns about the Saturday night debate schedule and its impact on the ability of campaigns to get their message out.

"We are taking on the establishment and I'm sure that there are people in the Democratic establishment not happy with the success that Sen. Sanders has had."
