The Council on American-Islamic Relations, or CAIR, has named Indiana University a “hostile campus” for targeting anti-genocide students and faculty.

CAIR is the largest Muslim civil rights and advocacy organization in the U.S., and on Thursday they designated IU a hostile campus. The group says this was due to severe disciplinary measures taken by the school’s administration against those “expressing opposition to occupation, apartheid, and genocide.”

This has included mass arrests, suspension of faculty members, campus bans, and the use of militarized police forces to dismantle peaceful demonstrations.

The group says IU President Whitten has allegedly admitted to working with pro-Israel organizations to suppress speech critical of Israel, a violation of free speech.
