Crowds gather to see Washington's cherry blossoms
Despite warnings from public health officials to maintain at least a 6-foot distance from other people, hundreds of visitors crowded onto the National Mall Saturday to see the cherry blossoms.
This prompted the National Park Service, which oversees the grounds, to issue warnings throughout the day to help prevent the spread of COVID-19.
In one tweet, the National Park Service said it was becoming "increasingly difficult to maintain effective social distancing and keep an appropriate space from other people."
Several hours later, NPS tweeted again, announcing access to parking near the cherry blossoms would be restricted on Sunday as result of Saturday's crowds.
