United States Senate begins Navy pobe. These three United States Senators were named a subcommittee by the Senate Naval Affairs Committee to conduct the Senate's inquiry whether American ship-building concerns attempted to break down the tri-power naval disarmament conference at Geneva in 1927. They will also investigate the propaganda activities of William B. Shearer against naval reduction. In the photograph. left to right: Senator Samuel M. Shortridge of California; and Senator Joseph T.
