A core group of Republican Senators, led by Chuck Hagel of Nebraska, spearheaded Congressional opposition to limits on greenhouse gas emissions. In February, 2001, Hagel was concerned that Clinton holdovers within the new administration might continue to conduct international negotiations that would bind the U.S. to climate controls. On March 1, 2001, Secretary of Commerce Don Evans faxed a package of documents to Secretary O'Neill that alerted the Treasury secretary to Hagel's worries. The package included an anonymous letter on State Department stationery warning that two Clinton administration holdovers "are seeking to box the Bush administration into a corner where it will have to choose between a bad deal and international embarrassment." Both men were gone within five months. Click here to go directly to the letter.
