Masks are again required for members of the House side of the U.S. Capitol amid a nationwide rise in coronavirus cases. Under the reimplemented mandate, members, both vaccinated and unvaccinated, must wear a "well-fitted, medical grade, filtration face mask" in House office buildings, during meetings and while in the House chamber. Under the order from Dr. Brian Monahan, Congress' attending physician, the new rule doesn't affect members of the Senate.
