The America First movement played a significant role in the podcast episodes, as it was portrayed as a vehicle for Nazi sympathizers and members of Congress to undermine American democracy.

The movement is mentioned in several episodes, including Bonus Episode: Rachel Maddow in Conversation with Tony Kushner, Episode 7: Rinse, Repeat, Episode 5: Shut It Down, and Episode 4: A Bad Angle.

The movement's connections to the Nazi propaganda operation and its involvement in efforts to subvert American democracy are central to the storyline of the podcast.
