I think the Senate has no right to negative the grade . The Constitution has divided the powers of government into three branches, Legislative, Executive and Judiciary, lodging each with a distinct magistracy. The transaction of business with foreign nations is Executive altogether. It belongs then to the head of that department, except as to such portions of it as are specially submitted to the Senate.
Exceptions are to be construed strictly.
This analysis calls our attention to the strict import of each term. The natural order of all these is 1. destination. The Constitution, analysing the three last, shews they do not comprehend the two first. The Senate is not supposed by the Constitution to be acquainted with the concerns of the Executive department. All this is left to the President.
