An elementary school teacher from Des Moines is on leave after showing her students a questionable video. The mother of one of the nine-year-old students at Wright Elementary says the video amounts to pornography.

Art teacher Karen Maresh reportedly showed the video in class about an artist, Keith Haring. School district officials say Maresh was put on paid leave Monday after the video was shown last week. It included a host of Haring’s works, including the alleged obscene images of sexual acts and genitalia.

One of Haring’s sculptures, depicting three colorful dancing figures, was put on display in a downtown sculpture garden in Des Moines last week.
