Rep. Ilhan Omar, one of two Muslim women elected to Congress last November, wears a hijab or headscarf as part of her religious observance. In January, lawmakers voted to accommodate Omar by ending a 181-year rule that banned headgear on the House floor.

The new representative from Minnesota tweeted, “I thank my colleagues for welcoming me,” and for making the Congress “more inclusive for all.” The change was applauded by Jewish voices, including Avi Shafran, spokesman for the Orthodox organization Agudath Israel: “Just as we would want a Jewish congressman to be able to wear a yarmulke (religious skullcap) in chamber, we would want a Muslim or Sikh representative to be able to hew to his or her religious convictions.”
