Who they are, where they came from

Ron Johnson serves as the senior United States Senator from Wisconsin, a seat he has held since January 2011. Before entering politics, Johnson was chief executive officer of a plastics manufacturer in Oshkosh, Wisconsin. He was first elected to the Senate in 2010, defeating Democratic incumbent Russ Feingold, and subsequently won reelection in 2016 in a rematch against Feingold and again in 2022 in a narrow race against Lieutenant Governor Mandela Barnes. In the Senate, Johnson has sponsored legislation across a range of policy areas. He introduced the No WHO Pandemic Preparedness Treaty Without Senate Approval Act (S.1983), which would require Senate ratification of any World Health Organization pandemic preparedness treaty. He sponsored the Right to Treat Act (S.1830) and the Stopping Overdoses of Fentanyl Analogues Act (S.165), addressing medical treatment access and drug scheduling, respectively. He introduced the Midnight Rules Relief Act of 2025 (S.164) and the GOOD Act (S.252), both related to federal regulatory processes. Johnson also sponsored the CURD Act (S.184), which addresses cheese standards of identity, reflecting Wisconsin's dairy industry. Additional sponsored measures include the SOAR Permanent Authorization Act (S.3710), the Interstate Commerce Simplification Act of 2025 (S.3027), the Safe Routes Act of 2025 (S.1063), the Shutdown Fairness Act (S.3012), and a bill to direct the U.S. Fish and Wildlife Service on specific administrative requirements (S.1306). He introduced amendments under both the 118th and 119th Congresses (SAMDT.11, SAMDT.3428).
