As they prepare to welcome two newly-elected Muslim women into the 116th Congress, Democrats have proposed a clarification to a 181-year-old rule banning representatives from wearing hats on the House floor. If approved, the new rules would allow lawmakers to wear religious headwear, like hijabs and kippahs, once Democrats take control of the chamber in January. Representative-elect Ilhan Omar, one of the first two Muslim women to serve in Congress, wears a headscarf. She was born in Somalia and came to the United States as a refugee.
