A Palmdale history teacher has been placed on administrative leave for the second time in two months after students accused her of repeatedly making inappropriate and racist comments targeting Latino and black children in class.

Students at Space and Aeronautics Gateway to Exploration Magnet Academy said that the teacher has praised President Trump’s border wall, saying Mexicans should go back to their country, and that she would “bring back” slavery. The teacher, who has not been identified, also said she would torture students and made comments about eating human flesh, classmates told school officials.
