Adams had the opportunity to fill three Supreme Court vacancies during his term in office. In December 1798, the Senate confirmed Adams's nomination of Bushrod Washington, nephew of former president Washington, to succeed Associate Justice James Wilson. One year later, Alfred Moore succeeded Associate Justice James Iredell. Then, in January 1801, Adams named John Marshall as the Supreme Court's fourth Chief Justice, replacing Oliver Ellsworth, who had retired due to ill health. Adams had initially nominated former Chief Justice John Jay, but Jay declined to return to his former position. Marshall, who was serving as Secretary of State at the time, was quickly confirmed by the Senate, and took office on February 4. He continued to serve as Secretary of State until Adams' term expired on March 4.
