Think tank to sue Treasury to make carbon tax proposal emails public

A conservative Washington think tank will file suit Tuesday seeking to force Treasury Secretary Timothy Geithner to make public more than 7,300 internal emails circulated in recent months among senior executives in his department about a carbon tax proposal officials say taxpayers don’t need to know about.

The Competitive Enterprise Institute will file the suit in federal district court tomorrow because Treasury Department officials denied the non-profit organization’s request for a waiver of reproduction fees under the federal Freedom of Information Act.
