President Donald Trump lashed out at the Supreme Court Wednesday on Truth Social, expressing his anger for overturning his landmark tariffs and calling the court’s first Black female justice, Justice Ketanji Brown Jackson, a “Low IQ person”—despite criticism his frequent use of the insult is a racist, sexist trope.

Trump complained that liberal justices consistently vote as a block, while some conservative justices often break with the majority to rule unfavorably against Trump, most notably in overturning his tariffs.
