In debate on the floor of the United States Senate over the Respect for Marriage Act, a letter co-written by Professor Robin Fretwell Wilson was cited multiple times. The letter, written along with Douglass Laycock of the University of Virginia, Thomas Berg of the University of St. Thomas, and Carl Esbeck of the University of Missouri, explained that beliefs regarding marriage, including certain faith traditions, would be protected under the clauses of the act while also ensuring thousands of federal benefits tied to marriage will continue to be available to same-sex and interracial couples. The Act passed the Senate 61-36 and was signed by President Joe Biden in December.
