President Trump and Stormy Daniels. (Carolyn Kaster, Matt Sayles/AP)

The contract dispute between Stormy Daniels and President Trump seems to me to be rather easily resolved [“Stormy Daniels sues Trump over nondisclosure deal,” Politics & the Nation, March 7]. The essence of the contract appears to be an unlawful violation of campaign finance laws. As such, it is unenforceable. It is a fundamental principle in contract law that no contract whose essence is an unlawful purpose can be enforced, and it is in fact null and void.
