After his father's death, Roosevelt had inherited $125,000 (equivalent to $3.3 million in 2019), enough to live comfortably for the rest of his life. Roosevelt gave up his earlier plan of studying natural science and instead decided to attend Columbia Law School, moving back into his family's home in New York City. Roosevelt was an able law student, but he often found law to be irrational. He spent much of his time writing a book on the War of 1812. Roosevelt was a member of the New York State Assembly (New York Co., 21st D.) in 1882, 1883 and 1884. Roosevelt exposed suspected collusion in the matter by Judge Theodore Westbrook, and argued for and received approval for an investigation to proceed, aiming for the impeachment of the judge.
