Britt Grant? She hasn’t even been confirmed to the 11th Circuit yet, but Trump could point to her service in the Supreme Court of GA. And she’s from Stanford Law, so she would break the Harvard/Yale monopoly while still being from a top-3 (or at least top-5) law school.
I just realized that the second woman might be Joan Larsen, who turns 50 in December. She served in the MI Suprene Court and last year was confirned as a judge in the Court of Appeals for the 6th Circuit.
