New Federal Highway Adminstration chief Nicole Nasen fought EPA climate rules

Nicole Nason, the new head of the Federal Highway Administration, tried to delay EPA efforts to regulate greenhouse gas emissions from cars under President George W. Bush, according to three people familiar with the events.

The claims come two weeks after Nason sailed through her Senate confirmation with an overwhelming vote of 95-1, earning bipartisan praise along the way.

As FHWA administrator, Nason has broad authority over efforts to assist state and local transportation agencies with sustainability and climate goals. Nason was previously tapped by Bush to lead the National Highway Traffic Safety Administration, another division of the Department of Transportation, in January 2006.
