MADISON, Wis. (AP) — University of Wisconsin-Oshkosh officials are investigating racist images circulating on social media involving students.

Chancellor Andrew Leavitt says university officials learned early Friday morning of photos posted to Twitter showing a whiteboard sign in an off-campus house that said "No Liberals, Jews, Muslims, Queers or Hmongs." Another photo showed a swastika hanging on the wall during a party at the house.

Leavitt says the dean of students and university police spoke with two students who live at the house on Friday.

Leavitt says students have a constitutional right to say what they want but investigators are looking into whether they disrupted the university, threatened or harassed anyone. Sanctions can include expulsion.

Leavitt convened a public forum Friday afternoon to discuss the images. He says several hundred students attended.
