President-elect Trump has nominated Fox News personality Sean Duffy as secretary of transportation. In the 1990s, Duffy starred in MTV reality TV shows including “The Real World: Boston” and “Road Rules.” Duffy served five terms as a Republican congressmember representing northern Wisconsin until 2019, when he resigned from Congress. In 2016, he authored the PROMESA Act, which created an unelected, federally appointed control board with sweeping powers to run Puerto Rico’s economy. Duffy has a 2% lifetime score from the League of Conservation Voters. He has previously blamed the sun — rather than human activity — for global heating and has promoted what he called “alternative science” challenging the overwhelming scientific consensus on the climate crisis.
