Elizabeth leads Cooley’s Supreme Court and appellate practice group and is widely considered one of the nation’s top appellate lawyers. Elizabeth served as the 48th Solicitor General of the United States from 2021 to 2025. As Solicitor General, she was responsible for conducting and supervising all Supreme Court litigation on behalf of the United States and overseeing the federal government’s appellate strategy in lower courts throughout the country. She has argued 35 cases in the Supreme Court, delivering more Supreme Court arguments since 2021 than any other advocate. Her matters have included some of the most high-profile, consequential cases of our time, implicating pressing and complex issues of constitutional law, administrative law, taxation, statutory interpretation, criminal law, environmental regulation, technology, civil rights, and antitrust. Law360 described Elizabeth as “acclaimed for her oral advocacy in the U.S. Supreme Court’s biggest cases” and said she is a “once-in-a-generation talent who uses her seemingly endless knowledge of case facts and related law” to achieve success on appeal.
