The letter is a response to Mr. Edward B. Massie's request for support on HR 5494, a bill related to his military record and medical attention in 1918. The sender, George B. Schwabe, advises against forwarding the letter to the President as it may not reach him personally and emphasizes the separation of powers between the Executive and Legislative branches of government. Schwabe expresses his willingness to support Massie's case before the Committee on Pensions and keep him informed on any updates.
