Computer system used by Clinton campaign hacked

Hillary Clinton's presidential campaign says a computer system connected to the campaign has been hacked.

Campaign aides say the intrusion was part of a larger breach of the Democratic National Committee that was made public earlier this week, when WikiLeaks released the organization's private emails.

The violation concerned a DNC analytics data program used by the campaign and a number of other organizations.

Spokesman Nick Merrill says a review conducted by outside cyber security experts has found "no evidence" that the campaign's "internal systems have been compromised." The campaign refused to give additional details about the program or nature of the attack.
