US Presidency
1910

The regulation of interstate and foreign commerce is certainly conferred in the fullest measure upon Congress, and if for the purpose of securing in the most thorough manner that kind of regulation, Congress shall insist that it may provide and authorize certain agencies to carry on that commerce, it would seem to be within its power. This has been distinctly affirmed with respect to railroad companies doing an interstate business and interstate bridges. The power of incorporation has been exercised by Congress and upheld by the Supreme Court in this regard. Why, then, with respect to any other form of interstate commerce like the sale of goods across State boundaries and into foreign commerce, may the same power not be asserted? Indeed, it is the very fact that they carry on interstate commerce that makes these great industrial concerns subject to Federal prosecution and control.
