He was a member of the New York State Assembly in 1812–13.
In April 1814, John ran as a Federalist for the 14th United States Congress, and was declared elected due to a mistake made by the deputy county clerk who had transcribed the returns. Credentials were issued by the Secretary of State of New York, but John Adams did not take or claim the seat. His Democratic-Republican opponent Erastus Root contested Adams's election and was seated on December 26, 1815.
