ABC News’ Devin Dwyer reports: If you thought Supreme Court justices are exempt from jury duty in their local courts, think again. Justice Elena Kagan was spotted among a crowd of prospective jurors huddled in a waiting lounge this morning at D.C. Superior Court. Sporting dark trousers and a checkered patterned sweater jacket, she sat quietly, reading through what appeared to be a legal brief and making handwritten notes in the margin. As of this writing, she hasn’t been called to step forward and fulfill her civic duty. But if she does make it through voir dire — the questioning of potential jurors on their backgrounds and biases — she would have a few free days to sit for a trial. The Supreme Court does not return to the bench to hear oral arguments until the end of February. UPDATE, 2:19 pm ET: All the remaining jurors have been released, including Kagan. She was seen chatting warmly with a handful of people who recognized her. Then, Kagan dropped her plastic badge in the trash can and left the courthouse without stopping to collect her $4 transportation stipend.
