From this morning's Earlybird:

• "Congressional investigators on Thursday uncovered yet another forged letter sent to a House Democrat purportedly from a local nonprofit -- but actually from a Washington, D.C., lobbying firm -- urging opposition to controversial climate change legislation," Roll Call (subscription) reports. "The discovery means that at least 14 fraudulent letters were sent by Bonner & Associates, a subcontractor for the American Coalition for Clean Coal Electricity, to at least three different House Members in an effort to sway their votes on the climate change bill before it narrowly passed the House in June."

• Senate Majority Leader Harry Reid, D-Nev., "has come down on the side of a labor-backed petition for relief from a surge in Chinese tire imports this decade, making good on a pledge to United Steelworkers union president Leo Gerard," CongressDailyAM (subscription) reports. "'Such relief is important to the tire industry, and the workers and communities it supports throughout America,' Reid wrote" to President Obama "in a letter dated Sept. 2."

• "Six of Washington's biggest business lobbies are urging lawmakers to boost the nation's debt limit above $12.1 trillion as the economy confronts historic mountains of red ink," The Hill reports. "The associations said in a letter on Thursday that it is 'critical to ensuring global investors' confidence in the creditworthiness of the United States, that Congress approve the administration's request for a higher debt limit.'"
