William McKinley actually said...
I, William McKinley, President of the United States, by virtue of the power vested in me by the Constitution and the laws, and deeming sufficient occasion to exist, have thought fit to call forth, and hereby do call forth, volunteers to the aggregate number of 75,000 in addition to the volunteers called forth by my proclamation of the 23d of April, in the present year, the same to be apportioned, as far as practicable, among the several States and Territories and the District of Columbia according to population and to serve for two years unless sooner discharged.
