Biography
F. H. Shoemaker, identified as a Farmer-Labor congressman, was arrested while supporting Minneapolis City Market strikers before the May 1934 settlement, according to the June 5 account. The report supplies no exact arrest or release day, charge or measured custody duration for this picket-line episode. It separately recalls a year served at Leavenworth for writing a letter to a banker political opponent; that earlier imprisonment is not the 1934 strike arrest. Daily Worker, June 5, 1934, page 5.

Page 2’s May 22 dispatch already reports the congressman’s Minneapolis strike-picket arrest, narrowing the reporting upper bound for the existing episode. It supplies no exact arrest or release day; the episode is not a new case. Source: https://www.marxists.org/history/usa/pubs/dailyworker/1934/v11-n123-may-23-1934-DW-LOC.pdf
