The United States House of Representatives ban on head covering is an 1837 simple resolution that is a sumptuary rule restricting Representatives from wearing any headgear during sessions. It originally represented a break from the British House of Commons hat-wearing tradition. After 181 years, in 2018 a partial repeal to allow religious accommodation for a number of faiths that practice head covering was proposed with the election of Ilhan Omar, who wears a hijab.
