The University of Iowa is trying to figure out who is behind offensive fliers found on campus. The fliers target the Latino, Native American, African American and LGBTQ communities.

On October 10th, someone first found fliers near the campus’s Latino Native American Cultural Center, LGBTQ Resource Center and Afro-American Cultural Center.

Just this past Sunday, a resident assistant discovered a bulletin board in a residence hall with fliers with similar messages.

Some of flyers read “are you sick of anti-white propaganda in college.” Another one reads “we have a right to exist.” The flyers cover Hillary Clinton yard signs
