Horace Gray, Johnson v. Sayre — Opinion of the Court
“ Congress is thus expressly vested with the power to make rules for the government of the whole regular army and navy at all times, and to provide for governing such part only of the militia of the several states as, having been called forth to execute the laws of the Union, to suppress insurrections, or to repel invasions, is employed in the service of the United States. ”
