On October 30, 2017, Vanity Fair published an interview with former Speaker Boehner, who said of the Freedom Caucus: “They can’t tell you what they’re for. They can tell you everything they’re against. They’re anarchists. They want total chaos. Tear it all down and start over. That’s where their mindset is.”
