Adam Daniel Kinzinger is an American retired politician, political commentator, and former Air National Guard officer. A member of the Republican Party, he served as a U.S. representative from Illinois from 2011 to 2023; representing Illinois's 11th congressional district and later Illinois's 16th congressional district.
Kinzinger was first elected to Congress in 2010 from the 11th district. His district was largely merged with the 16th after the 2010 census, and Kinzinger transferred to the 16th after defeating its incumbent, Don Manzullo, in the Republican primary. After President Donald Trump lost the 2020 presidential election, Kinzinger became known for his vocal opposition to Trump's claims of voter fraud and attempts to overturn the results.
Kinzinger did not seek reelection to Congress in 2022. After leaving office, he joined CNN as a senior political commentator.
