"Koch believes that Obamacare will increase deficits, lead to an overall lowering of the standard of health care in America, and raise taxes," the letter said. "However, Koch has not taken a position on the legislative tactic of tying the continuing resolution to defunding Obamacare nor have we lobbied on legislative provisions defunding Obamacare."
The letter was sent by Philip Ellender, president of government and public affairs for Koch Companies Public Sector, LLC. It was not immediately clear if the letter was sent to all senators.
Koch Industries is headed by billionaire brothers Charles and David Koch, who are major contributors to various conservative causes. A New York Times story on the origins of the defund Obamacare fight noted that groups that received Koch support have been significant forces in opposing the health care reform law.
