The Democratic National Committee has told the campaign of Senator Bernie Sanders of Vermont that it was suspending its access to its voter database after a software error enabled at least one of his staff members to review Hillary Clinton's private campaign data.<br />"The D.N.C. was notified on Wednesday by its data systems vendor NGP VAN that as a result of a software patch, all users on the system across Democratic campaigns were inadvertently able to access some data belonging to other campaigns for a brief window," said the committee's communications director, Luis Miranda.<br />He added: "We have also instructed NGP VAN to conduct a full audit of the system to ensure the integrity of the data and the security of the system for the campaigns that use it, and to begin a review process with every campaign and user to ensure they understand and abide by the rules governing the use of the system.
