After Big Cass was released from WWE back in 2018, several reasons were reported to have contributed to the company's decision to fire the former NXT star.

One of these reasons was a backstage argument with former NXT Champion Sami Zayn. Throughout his career, Cass was known to be a big supporter of United States President Donald Trump, which led to several issues for Cass when it came to his view on politics.

According to reports, Zayn and Cass got into a heated argument about the treatment of Muslims. Whilst this seemingly wasn't the main reason for WWE to make their final decision, it was reported to have upset a number of stars backstage. Reports suggested that many stars changed their opinion of Cass following the altercation.

Cass had a number of issues backstage in his final few weeks with WWE and, if true, the argument with Zayn didn't do very much for his reputation.
