Mark Kelly

Mark Kelly is a Democratic U.S. Senator representing Arizona since December 2020, following a distinguished career as a U.S. Navy combat aviator and NASA astronaut—he logged over 50 days in space across four shuttle missions, including commanding the final flight of Endeavour. In the Senate, he has championed public service-focused legislation—advocating for gun-safety reforms, infrastructure investments, affordable healthcare access, lower prescription drug costs, and transparency in government—while maintaining a centrist appeal to both Democrats and independents.
