Why did the DNC let the Bernie-Hillary story leak?

The breach occurred after a software problem at the technology company NGP VAN, which gives campaigns access to the voter data. The problem inadvertently made proprietary voter data of Mrs. Clinton's campaign visible to others, according to party committee officials. The Sanders campaign said that it had fired a staff member who breached Mrs. Clinton's data. But according to three people with direct knowledge of the breach, there were four user accounts associated with the Sanders campaign that ran searches while the security of Mrs. Clinton's data was compromised.
