Speaker Nancy Pelosi and Capitol officials issued broad new mask requirements Wednesday after a Republican member of Congress tested positive for the coronavirus. The member, Texas Rep. Louie Gohmert, often shunned wearing masks and was known to vote without one. Pelosi announced Wednesday evening that all members will be required to wear a mask when voting on the House floor and that one will be provided if anyone forgets. Several hours later, the House sergeant-at-arms and the Capitol’s top physician issued an order requiring masks inside House office buildings, with few exceptions. That mandate goes into effect at 8 a.m. Thursday. Pelosi said failure to wear a mask on the House floor is a “serious breach of decorum” for which members could be removed from the chamber.
