Interesting report on Buzzfeed.
http://www.buzzfeed.com/evanmcsan/bernie-sanders-campaign-accessed-confidential-clinton-data#.btmw43MNvThe Bernie Sanders campaign accessed confidential data from the Clinton campaign through a DNC voter database.
The DNC suspended the Sanders campaign's access to the data, which is key for early caucuses and primaries, until they can be sure that the information has been deleted.
The Sanders campaign fired the person who accessed the data.
I'm a bit perplexed at the punishment because it seems they did everything right, pointing out the flaw to the vendor.
