The deans of the five law schools within the University of California system have banded together to defend critical race theory in the face of attacks from the Trump administration, which recently barred federal employers from offering training on the subject.

In a joint letter issued Friday, the deans said that critical race theory—in which culture and society is examined through the lens of race and power—is a valuable and necessary tool to better understand our country, legislation, and the courts. And many of the professors on their faculties specialize in critical race theory, they noted.
