What authority does the President have regarding treaty negotiation?

The President has the authority to negotiate treaties, and for these treaties to become legally binding, they must be ratified by a two-thirds vote in the Senate. This process is outlined in Article II, Section 2 of the Constitution, which explicitly states that the President shall have Power, by and with the Advice and Consent of the Senate, to make Treaties, provided two-thirds of the Senators present concur. This demonstrates the system of checks and balances, where the President plays a crucial role in foreign policy through negotiation, but the Senate retains significant power by requiring a supermajority to ratify treaties. This ensures that treaty obligations have substantial bipartisan support before the United States is bound by them.

The options that suggest other processes either misunderstand or misinterpret the constitutional framework regarding treaty negotiation and ratification.
