Leonard is well known among the gaming community and announced in June 2019 that he partnered with FaZe Clan. However, Scuf Gaming and Origin PC both announced after the video emerged that they had ended their working relationships with the Miami big man while they reviewed his actions.
Leonard used the slur at a time when anti-Semitism has been on the rise in the United States.
The Anti-Defamation League reported anti-Semitic acts increased in 2016 after dropping for approximately 15 years, while the American Jewish Committee noted an FBI Hate Crimes Statistics Report determined 60 percent of religious-based hate crimes in 2019 were directed toward Jewish people, though they make up less than two percent of the American population.
On the court, Leonard has appeared in just three games this season for the Heat.
