This year’s Oscar nominees are overwhelmingly white, and while host Chris Rock didn’t address that in a new teaser for the Feb. 28 ceremony, he was sure to point it out in a tweet on Friday.

“The #Oscars,” he wrote while sharing the new clip. “The White BET Awards.”

The tweet comes a day after Academy president Cheryl Boone Isaacs commented on the lack of diversity to Deadline. “Of course I am disappointed, but this is not to take away the greatness [of the films nominated],” she said. Others have been more explicitly critical: The Los Angeles chapter of the National Action Network has called for a boycott of the show, calling “the lack of African Americans and women” on the list of nominees “appalling.”

The Rev. Al Sharpton has also been vocal about his disapproval. “Yet again, deserving black actors and directors were ignored by the academy — which reinforces the fact that there are few if any blacks with real power in Hollywood,” he said in a statement. “Being left out of awards consideration is about more than just recognition for a job well done; winning an Oscar has long-lasting cultural and economic impacts.”
