Shipstead (MN, Farm-Labor, then Republican) testified to the Senate Committee on Immigration concerning the Nye Resolution to revised the National Origins clause of the Immigration Law. He was generally an isolationist, this legislator from Minnesota observed:

I would like to know how this Committee of ‘experts’ discovered that the population of the United States prior to 1790 were not immigrants or the children of immigrants. .  . . I know of no provision of law nor do I desire any such that may prohibit those whose ancestors were here before 1790 from purchasing for themselves championship belts for the purpose of designating to the world that they are the only ‘simon pure’ Americans. But for purposes of Legislation we cannot distinguish or give any preferred status to any particular group.
