Abe is pretty much back to normal: The Lincoln Memorial has reopened to the public after someone splattered green paint on the lower part of the statue early yesterday morning. Crews cleaned the marble icon with pressure hoses and chemical paint remover, reports AP, and the green is now mostly gone. The crews will keep working at it over the weekend. "It is not permanent damage," says a National Park Service spokeswoman. NBC4 Washington reports that police have surveillance video of the vandal and are "seeking a person of interest." Authorities aren't releasing any details about the investigation, however.
