As House leaders begin drafting articles of impeachment, examples from the Nixon and Clinton eras abound. This week, On the Media rewinds to the 19th century — and the turbulent impeachment of Andrew Johnson. Plus, what a debate between two right-wing intellectuals means for the future of conservatism.

1. Brenda Wineapple, author of The Impeachers, on the acrimonious trial of Andrew Johnson. Listen.

2. Matthew Sitman [@MatthewSitman], co-host of the your-enemy-1682b684.simplecast.com/">Know Your Enemy podcast, on the rise of illiberalism among the conservative intelligentsia. Listen.
