Reports Fox News:
Sen. Orrin Hatch is calling on the IRS to investigate whether someone on the inside could have leaked the private tax files of a prominent anti-gay marriage group.
Hatch, in a letter Tuesday to IRS Commissioner Douglas Shulman, said, "evidence suggests that the IRS may have been the source of the unauthorized disclosure of donor information."
The Republican Utah senator was referring to the recent publication of documents listing 2008 contributors to the National Organization for Marriage. Among those contributors was Mitt Romney.
