Democratic Presidential candidate Bernie Sanders' campaign has threatened to sue the DNC for suspending access to the national voter database. The DNC said Sanders staffers reviewed Hillary Clinton's campaign data after a software error, Politico reports. Sanders' campaign says the suspension undermines the senator's run, and even suggested the DNC leaders support Clinton and are working to 'sabotage' his campaign. Sanders' campaign manager Jeff Weaver also said they believe some of their data was lost to another campaign. Weaver said the campaign fired the staffer who was in charge of the breach.
