Clancy, and his son Francis Kennedy, were indicted by a federal grand jury for violating the postal laws, where they were accused of having leaked the questions (which had been sent by mail) for a civil service test. He ran unsuccessfully for the United States House of Representatives in 1920, as the Democratic candidate for New York's 1st congressional district. He was again a member of the NY State Assembly Community Board 3 from 1923 to 1926. He was a member of the New York State Senate from 1927 to 1930, and then was appointed Public Administrator of Queens in May 1930.
