Leo is best known as the kingpin of a decades-long effort to pack the federal judiciary with conservative judges. As the leader of the Federalist Society, Leo assembled a vast and secretive network of wealthy donors and nonprofits to amplify the power of the conservative legal movement, culminating in Leo handpicking the list of former President Donald Trump’s potential nominees to the Supreme Court. While some of his efforts are highly public, others, like the funding of Do No Harm, occur with little fanfare.

The medley of conservative groups channeling money to Do No Harm underscores the growing belief on the right that attacking trans rights is “a political winner.”
