Lincoln Memorial, Washington Monument Vandalized

The National Park Service says graffiti has been found at the Lincoln Memorial, the Washington Monument, and the World War II Memorial, the AP reports. US Park Police spokeswoman Sgt. Anna Rose said Tuesday that the messages written in permanent marker were discovered over the holiday weekend. Similar graffiti was found on a power box along the National Mall. Rose says the message written on the Washington Monument references President John F. Kennedy's assassination and the 9/11 attacks, but did not provide specifics. Authorities think the graffiti was left by the same person. (More Lincoln Memorial stories.)
