Two more Washington landmarks have been vandalized with green paint, News4 has learned.
Just three days after paint was found splattered at the Lincoln Memorial, a similar substance was discovered at the National Cathedral and on a statue memorializing Joseph Henry, the first secretary of the Smithsonian Institution.
National Cathedral officials confirmed green paint was found on an organ inside the historic Bethlehem Chapel. The paint was still wet Monday.
The entire lower level of the cathedral is closed while police search the building.
Paint was also found on the front and back of the Joseph Henry statue's pedestal. The statue is located outside the Smithsonian castle, near the merry-go-round on the National Mall.
While the paint at the Lincoln was splattered on, the paint on the Henry statue resembles finger painting, reported News4's Mark Segraves.
It's unclear when the statue was vandalized. U.S. Park Police were alerted Monday morning to that incident.
U.S. Park Police are investigating whether the case at the Henry statue is linked to the incident at the Lincoln Memorial, Linda St. Thomas of the Smithsonian told News4.
"It is [the] Smithsonian's job to remove the paint -- from [the] granite base and bronze statue," she said. "We have to find a product that will not damage the protective coating."
St. Thomas said they should be able to remove the paint within a couple of days.
