At Tuesday’s confirmation hearing for Supreme Court nominee Ketanji Brown Jackson, senators asked the judge about criminal sentencing, faith, and family. Ted Cruz had a different topic in mind, though: children’s books.

The Texas Republican grilled Jackson, who, if confirmed, would be the first Black woman on the Supreme Court, about books in the curriculum of Georgetown Day School in Washington, D.C. Jackson serves on the board of the school.

Cruz said the school’s curriculum was “filled and overflowing with critical race theory.” He singled out one book from the curriculum: Antiracist Baby by Ibram X. Kendi, illustrated by Ashley Lukashevsky.

Using large posters of pages from the book as props, Cruz quoted sections in which Kendi writes that children can learn racism from adults, and should confess when they act in a racist manner.

“Do you agree with this book that is being taught to kids that babies are racist?” Cruz asked.

“Senator,” Jackson said with a sigh, “I do not believe that any child should be made to feel as though they are racist, or though they are not valued, or though they are less than, that they are victims, that they are oppressors. I don’t believe in any of that.”

Kendi took note of the exchange on Twitter, writing, “You know Judge Ketanji Brown Jackson has impeccable credentials—and you know you’re doing the work—when @tedcruz questions her about your books since he can’t touch her record.”
