Adam Daniel Kinzinger (; born February 27, 1978) is an American former politician, senior political commentator for CNN, and lieutenant colonel in the Air National Guard. He served as a United States representative from Illinois from 2011 to 2023. A member of the Republican Party, Kinzinger originally represented 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 was defeated in 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 was one of the 10 Republicans who voted to impeach Trump for incitement of insurrection in his second impeachment. He also voted to create the select committee to investigate the 2021 United States Capitol attack, to which he was subsequently appointed. Kinzinger did not seek reelection to Congress in 2022. After leaving office, Kinzinger joined CNN as a senior political commentator.
