Trivia: Who is the only Supreme Court justice to also become President?
John Quincy Adams
Millard Fillmore
William Taft
Grover Cleveland
The correct answer is William Taft
So why is this answer correct? : Eight years after serving one term as the country’s 27th President, William Howard Taft became the 10th chief justice of the Supreme Court in 1921. Taft was never a fan of politics, and his greatest aspiration was to join the Supreme Court, but his wife, Helen, pushed him toward the presidency, which he won over William Jennings Bryan.
