The Solicitor General of the United States is often referred to as the 10th Justice (the Supreme Court is made up of 9 justices — 8 associates and a Chief Justice) because the federal government’s representative before the Court argues before the court more than any other, uniquely does not have to ask the Court’s permission to file an amicus brief, and is often even asked to do so by the Court so that they may benefit from the S.G.’s perspective on a case.
Donald Verrilli, Jr. replaced Elena Kagan as Solicitor General after she was elevated to the Court itself. And he’s been paying interest on credit card debt for years — despite assets which would easily allow him to pay off his cards.
