Who is former Republican congressman Adam Kinzinger? Once a GOP stalwart, he blasted Donald Trump for the January 6 attacks – and now a documentary reveals the impact on his family

Republican Adam Kinzinger has spent the last few years as a lone wolf in party circles. The Illinois congressman served in office from 2011 to 2023, solidifying his strength in GOP circles. But when the attacks on Washington’s Capitol Building happened on January 6, 2021, he slammed former president Donald Trump for his role in the riots, and the broader Maga community for continuing to support Trump. Kinzinger went from inner-circle Republican heavyweight to supporting Democratic presidential hopeful Kamala Harris.

A recent documentary, The Last Republican, which details Kinzinger’s falling out with his party and the impact his stance has had on his family, had its premiere at the Toronto International Film Festival in September. The film reveals intimate details about Kinzinger’s decision to speak out, knowing the consequences.

Here’s what to know about the man who stood up to Trump and his loyalists.

According to The Washington Post, Kinzinger turned down 20 documentary offers before choosing to work with Steve Pink. The director of the 2010 science fiction-comedy Hot Tub Time Machine was interested in how standing up to Trump and the Maga squad had impacted Kinzinger’s personal life and family, per The Hollywood Reporter. “When I talked to Steve and the team, their interest was in the human element – what’s the cost to you and your future kid?” he shared.

Kinzinger was one of the first Republicans to speak out about Trump’s role in the January 6 attacks on the US Capitol. Per The Hollywood Reporter, he joined a mostly Democratic congressional commission, leading to his ousting from his party. Referred to by many as a lone wolf in his crusade against Trump, the Illinois Republican then chose not to seek re-election to Congress in 2022.
