The Committee on Public Information (CPI) is the first and only Ministry of Propaganda the United States has ever had. It started one week after the United States entered World War I in April of 1917; in fact, there wasn't even conscription for some weeks, but the Committee on Public Information was created right away. Why? To explore this question, and to learn more about the CPI, Andrew sat down with journalist, professor and Vietnam veteran Jack Hamilton (yes, actually sat down, like face-to-face, eyeball-to-eyeball!).
