Meanwhile, just so that they could piss off the libertarians, (aren't we glad that most Americans believe in the right of privacy) the GOP tried to pass a spending bill that included the following provision:
Hereinafter, notwithstanding any other provision of law governing the disclosure of income tax returns or return information, upon written request of the Chairman of the House or Senate Committee on Appropriations, the Commissioner of the Internal Revenue Service shall allow agents designated by such Chairman access to Internal Revenue Service facilities and any tax returns or return information contained therein.
Provision found at Talking Points Memo.
Thankfully this was caught and fought by the Democrats. Scary shit.
