Chuck Hurley, the intended nominee to oversee the National Highway Traffic Safety Administration, has withdrawn his name from consideration, according to the White House.

Hurley has been the Chief Executive Officer of Mothers Against Drunk Driving since 2005. His commitment to tougher fuel efficiency standards was being questioned by some environmental groups as were his ties to the auto industry. MADD receives funding from several automakers including Ford, Toyota and GM, according to the Washington Post.

NHTSA oversees highway safety programs and sets fuel efficiency and safety requirements for car companies.
