Question regarding Alan Dershowitz's former students. Which of them are Justices today?

Hi

About 9 minutes and 17 seconds into this video Alan Dershowitz mentions that his students have been/are Justices/ Supreme Court Justices. Who would they be exactly?

I look forward to your feedback.

Michael Avenatti, Alan Dershowitz debate gets personal

Kagan was one of his students.

Thanks puddleglum. Very helpful.
