MADISON, Wis. (AP) — University of Wisconsin-Oshkosh officials say they’re investigating racist images circulating on social media involving students and called a community forum to discuss them.

University spokeswoman Mandy Potts says officials became aware of the material Thursday that she said involved off-campus housing. An image posted on Twitter showed a whiteboard sign in the house that said, “No Liberals, Jews, Muslims, Queers or Hmongs.”

The same Twitter user posted another photo of a swastika hanging on a wall during a party at what appeared to be the same house.

Chancellor Andrew Leavitt sent a campus-wide email saying the school was aware of “racist messages and hateful symbols involving our students.” He called a forum Friday to discuss the images.

Leavitt said before the forum that university police and the Dean of Students Office were investigating.
