Ryan D. Nelson is a model of a modern anti-regulation conservative and culture warrior. As a Justice Department lawyer under President George W. Bush, he oversaw that administration's campaign to go easy on polluters and roll back environmental rules.
In a 2007 case, he argued that tuna should be labeled "dolphin-safe" even if caught in nets known to cause millions of dolphin deaths. In private practice, he filed a brief for seven states arguing that governments shouldn't be forced to upgrade their buildings in conformance with the Americans With Disabilities Act if the changes would cost money. His argument in the first case was rejected by an appellate court, and in the second by the Supreme Court.
Nelson's waffling about the human contribution to global warming at a Senate hearing on his nomination by President Donald Trump to a top Interior Department post prompted Trump to withdraw his nomination in 2018.
