Police in Oklahoma are investigating after racist, anti-gay and anti-Semitic remarks were found spray-painted on a second Democratic Party office as well as a nearby school and arts center.

Norman police spokeswoman Sarah Jensen says the vandalism was discovered early Wednesday on the windows and sidewalk outside the Cleveland County Democratic Party headquarters, the Firehouse Art Center and McKinley Elementary School.
