 This separation of powers between the President and Senate is also present in the (immediately preceding) Treaty Clause of the Constitution, which gives international treaty-making power to the President, but attaches to it the proviso of the Senate's advice and consent.Several framers of the U.S. Constitution explained that the required role of the Senate is to advise the President "after" the nomination has been made by the President.Roger Sherman believed that advice "before" nomination could still be helpful.
