Leonard Leo realized that in order to generate conservative rulings, the Supreme Court needs the right kind of cases. In the second episode of We Don't Talk About Leonard, ProPublica reporters Andrea Bernstein, Andy Kroll, and Ilya Marritz investigate the machine that Leonard Leo built across the country to bring cases to the Supreme Court and fill vacant judgeships, and the web of nonprofits he’s created through which to funnel dark money into judicial races.
