"The expediency of vesting the power of pardoning in the President has, if I mistake not, been only contested in relation to the crime of treason. This, it has been urged, ought to have depended upon the assent of one, or both, of the branches of the legislative body. I shall not deny that there are strong reasons to be assigned for requiring in this particular the concurrence of that body, or of a part of it. As treason is a crime levelled at the immediate being of the society, when the laws have once ascertained the guilt of the offender, there seems a fitness in referring the expediency of an act of mercy towards him to the judgment of the legislature. And this ought the rather to be the case, as the supposition of the connivance of the Chief Magistrate ought not to be entirely excluded."
