"These are the docs Rs don't want you to see—because they show that Judge Kavanaugh wrongly believes that Native Hawaiian programs are Constitutionally questionable.

"I think the testimony needs to make clear that any program targeting Native Hawaiians as a group is subject to strict scrutiny and of questionable validity under the Constitution," Kavanaugh wrote in the email thread.
