"The chamber of the Lincoln Memorial is shut down Friday morning because of vandalism. U.S. Park Police tell WTOP the Lincoln statue and the floor inside the memorial was splattered with green paint. They think the vandalism occurred at about 1:30 a.m."
According to WUSA-TV, "there is no estimate on how long the memorial will be closed to the public." Police will be studying surveillance video. The memorial is open 24 hours a day, 7 days a week.
