The letter, sent to Senate Majority Leader Harry Reid, bill co-authors John Kerry and Barbara Boxer, and Finance Chair Max Baucus was signed by senators from 14 Midwestern, coal-dependent states—including Minnesota's Al Franken and Amy Klobuchar, who are usually counted among Democrats supportive of climate legislation. The other signatories were Tom Harkin of Iowa, Michael Bennet and Mark Udall of Colorado, Kent Conrad and Byron Dorgan of North Dakota, Russell Feingold and Herb Kohl of Wisconsin, Carl Levin and Debbie Stabenow of Michigan, Sherrod Brown of Ohio, Roland Burris of Illinois, and Robert Byrd of West Virginia.
