The IRS has admitted they leaked information on donors of a conservative group to liberal activists during the 2012 presidential campaign season.

Donors to the National Organization for Marriage had their confidential tax information given to a group that actively opposed N.O.M. The list included Republican Presidential candidate Mitt Romney and his opponents used the information during the election cycle.

The confidential information was then given to websites like the Huffington Post.

After denying the IRS was the source of the information, the group has now virtually admitted they had leaked the information by paying $50,000 to N.O.M. over the leak.

The IRS still claims no guilt over the leak but says that the document leak was an “inadvertent mistake” because it “failed to redact confidential information.”

N.O.M. has asked the Department of Justice to offer immunity to the man given the confidential information so the IRS leaker can be brought up on charges. The Justice Department has so far refused to provide immunity or pursue prosecution of those who received the confidential information.
