After Washington Mayor Muriel E. Bowser (D) announced that masks will be required indoors starting Saturday even for people who are fully vaccinated, the Washington Nationals said they will change their policy beginning with Friday’s game against the Chicago Cubs.

Per the team, all fans, even fully vaccinated ones, will be required to wear an approved face covering in indoor areas at Nationals Park. This includes restaurants, retail stores, bathrooms, elevators and nursing mothers lounges.

The only exceptions to the policy are if fans are eating or drinking or if they are fully vaccinated in a suite with the glass open.

For those who are not fully vaccinated, face coverings are still required everywhere in Nationals Park and can only be removed temporarily while eating or drinking. The Nationals reopened Nationals Park to full capacity June 10.
