Answer
The resignation of Justice Abe Fortas arose due to a financial scandal. Specifically, Fortas had accepted a $20,000 a year retainer from the Louis E. Wolfson Foundation while he was serving as an Associate Justice of the Supreme Court. This revelation sparked an investigation by the Senate Judiciary Committee, leading to public criticism and calls for his resignation. Fortas eventually stepped down from the Supreme Court on May 14, 1969.
