Cite as: 596 U. S. ____ (2022) 15 KAGAN, J., dissenting at a time when he can return the favor—by a vote, a contract, an appointment. It takes no political genius to see the heightened risk of corruption—the danger of “I’ll make you richer and you’ll make me richer” arrangements between donors and officeholders. Section 304 has guarded against that threat for two decades, but no longer. In discarding the statute, the Court fuels non-public-serving, self-interested governance. It injures the integrity, both actual and apparent, of the political process. I respectfully dissent.
