Charity Struthers with Signature Tours brings a group of students into Lafayette Park, across the street from the White House, as it reopens in a limited capacity in Washington, Monday, May 10, 2021. Fencing remains in place around the park which will allow the Secret Service to temporarily close the park as they deem necessary. With COVID-19 numbers trending positive, officials in the nation’s capital have announced a pandemic reopening timeline that would see all indoor capacity limits eliminated by early June, but with mask requirements still in place.
