A Hawaii man convicted of attempted murder and assault wore blackface and gave a racist rant falsely equating himself to a black man during a sentencing hearing Monday.

“The reason why I’m like this is because I prepared myself to play my part in your kangaroo court, treating me like a black man. So today, I’m going to be a black man,” Mark Char told Hawaii circuit court judge Todd Eddins, according to video from Honolulu’s CBS affiliate KGMB.

Local officials told KITV that Char appeared to have obtained a permanent marker to blacken his face. Wearing blackface is a racist practice designed to mock black people that originated during minstrel shows in the 1800s.

Before his court appearance, Char refused requests from officials at his prison to remove the black marker from his face, according to KITV.
