In WhatsApp conversations leaked to the Miami Herald, participants used variations of the n-word more than 400 times, regularly described women as “removed,” used slurs to talk about Jewish and gay people and mused about Hitler’s politics.

Interspersed throughout were discussions about events promoting the Republican Party at Florida International University. The school told the Herald the chat logs are part of an ongoing criminal investigation.

The conversations included some of the campus’ top conservative leaders: the county GOP secretary, FIU’s Turning Point USA chapter president and the former College Republicans recruitment chair.
