Rapper Ice Cube was scheduled to appear on ABC's Good Morning America on Thursday to discuss the murder of George Floyd in Minneapolis.

But the ex-NWA member told his 4.9 million Twitter followers that he decided to cancel his appearance on the talk show at the last minute.

"I apologize to everyone expecting to see me on Good Morning America today, but after the events in Minnesota with George Floyd I'm in no mood to tell America, good morning," he tweeted.

Ice Cube, real name O'Shea Jackson, uses his platform to express the fears millions of Black men have as targets of police violence in America.

"How long will we go for Blue on Black Crime before we strike back???" he tweeted on May 26.

In another tweet, Jackson shared a photo of Derek Chauvin, the white cop who killed Floyd, who is Black. Chauvin's picture is next to a photo of a white supremacist wearing a "Make Whites Great Again" cap. His followers told him the man was not the fired cop, but Jackson retweeted his own tweet and wrote:

"The F.B.I. knows exactly who the racist are in each police department and still let them keep there jobs until something like this happens. Stop sitting on critical information. Weed them out and get them out...NOW!"
