On Thursday evening, Project Right Side and former RNC Chairman Ken Mehlman formally filed an amicus brief with the United States Supreme Court involving four landmark cases slated to be heard on April 28 concerning government recognition of the freedom to marry. A total of 303 Republican, libertarian, conservative and center-right high-profile activists and government officials – including past presidential candidates, seven current and former governors, twenty-three current and former members of the House of Representatives and U.S. Senate, and amici from thirty-three states – signed onto the brief. The brief was authored by pro bono legal teams at WilmerHale led by Reg Brown, Seth Waxman, and Alan Schoenfeld and at Polsinelli led by Sean Gallagher.
