What to know about Sean Duffy, Trump's choice to become transportation secretary

President-elect Donald Trump says he wants Sean Duffy to be his transportation secretary. That would position Duffy to oversee a complex system of pipelines, railroads, cars, trucks, airlines and mass transit systems, as well as funding for highways. Duffy is a former member of Congress who represented a Wisconsin district for nine years. He is the second Fox-affiliated TV host to be tapped by Trump. Duffy also has a background in reality TV, like Trump. He declined to run for governor of Wisconsin in 2022, despite Trump's urging, and is a former lumberjack athlete.
