The Prohibition Unit is reorganized into the Bureau of Prohibition.

General Lincoln C. Andrews, of World War I fame is appointed to the Assistant Secretary of the Treasury in charge of Prohibition in May of 1925. He assesses the current capabilities of the Prohibition Unit and in a 1927 Letter to the President of the Senate, states, "…This is a fair picture of the conditions today facing the executive department charged with the enforcement of the prohibition laws.
