Why isn't Eric Holder investigating the IRS for leaking the National Organization for Marriage's tax return?

Yes, the IRS is admitting someone at the IRS did this and is paying the legal fees of the National Organization for Marriage as a result.

The gay rights activist who received and disseminated the information, Matthew Meisel, “invoked his fifth amendment right not to incriminate himself” and he would not identify his conduit.

This all raises a question an honest media would ask: why has Eric Holder refused to investigate and prosecute this?

The American media will not ask this question because the National Organization for Marriage opposes gay marriage. The donors to the group, in the media’s mind, are bigots. To the American media they deserve no protection. They are oppressors.
