WASHINGTON, DC — The Lincoln Memorial was vandalized with a spray painted obscenity in large red letters on a pillar at the monument, The National Park Service announced.

The graffiti was found at about 4:30 a.m. Tuesday, officials said. It appears to say "F--- Law." A preservation crew is working to remove the graffiti and using a "mild, gel-type architectural paint stripper" to avoid damaging the stone, a press release from The National Park Service says. Officials say they will continue to clean until the evidence of the graffiti is gone.

— Sam Ford (@ABC7Sam) August 15, 2017 Back in February, someone defaced three D.C. national monuments — the Lincoln Memorial, Washington Monument and World War II Memorial — with permanent marker, scrawling bizarre messages referencing the assassination of John F. Kennedy and the Sept. 11, 2001 terror attacks.
