The defendant was convicted of transporting a female in interstate commerce for immoral purposes. Over the defendant's objection the trial court permitted testimony against him to be given by the defendant's wife. This ruling he assigned as error but held a wife is competent as a witness against her husband. Yoder v. United States, (C. C. A. 10th, 1935) 80 F. (2d) 665.
