After a fiery dispute and backlash from the progressive wing of the Democratic base, the Democratic National Committee (DNC) granted Bernie Sanders access to crucial voter files Saturday morning after suspending the 2016 candidate's campaign over a data breach.

The DNC temporarily suspended the Democratic presidential candidate's campaign from accessing important voter data on Thursday after four Sanders campaign staffers improperly accessed Clinton's voter files, reports Time. The DNC also accused Sanders of stealing from the Clinton campaign.

In turn, Sanders fired Josh Uretsky, the Sanders campaign's national data director. However, he alleged that DNC leaders were trying to undermine his bid for the White House by favoring his rival Hillary Clinton. The Sanders campaign also filed a lawsuit against the committee in U.S. District Court, accusing it of improperly cutting off the campaign's access to the voter data.

In addition, about 250,000 Democrats stood behind Sanders by signing a MoveOn.org petition supporting the Vermont senator, while Democrats for America (DFA) collected another 100,000 signatures.

Shortly before midnight, the DNC agreed to restore access to the files after Sanders.

"Based on this information, we are restoring the Sanders campaign's access to the voter file, but will continue to investigate to ensure that the data that was inappropriately accessed has been deleted and is no longer in possession of the Sanders campaign," DNC Chairwoman Debbie Wasserman Schultz said in a statement, reports Reuters.

"The Sanders campaign has now complied with the DNC's request to provide the information that we have requested of them," added Schultz.

The Sanders campaign also released a statement applauding he DNC decision to restore its access by Saturday morning.

"The Democratic National Committee on Friday capitulated and agreed to reinstate Sen. Bernie Sanders' campaign's access to a critically-important voter database," the Sanders campaign said in a statement.
