The Harley Krapohl papers consist of letters, photocopies of newspaper clippings, and a partially released Federal Bureau of Investigation file regarding the arrest and trial of George Viereck for violation of the Foreign Agents Registration Act in 1943. Viereck was an author who was a suspected Nazi propagandist in the United States prior to and during World War II. Senator Donald Riegle obtained the F.B.I. file for Mr. Krapohl, a former employee of the state of Michigan, through the Freedom of Information Act.
