Sanders’s campaign early Friday morning was blocked from accessing the DNC’s voter database after a security breach of private data belonging to Hillary Clinton’s campaign, caused by one of the DNC's vendors.

Sanders’s team responded furiously, tearing into the DNC in a fiery press conference and filing a federal lawsuit accusing the committee of trying to “tip the scales” in favor of Clinton in the Democratic presidential primary.
