It is the Secretary of State's job to negotiate treaties.

Yes
The secretary of state.
The president can negotiate treaties, but they must be ratified by the senate to go into effect. He can appoint ambassadors, and they also must be approved by the senate.
Through the Department of State and the Department of Defense, the President is responsible for the protection of Americans abroad and of foreign nationals in the United States. The President decides whether to recognize new nations and new governments, and negotiate treaties with other nations, which become binding on the United States when approved by two-thirds of the Senate. The president may also negotiate "executive agreements" with foreign powers that are not subject to Senate confirmation. I believe the president can negotiate treaties, but they do not take effect until the Senate votes to ratify them.
No treaty by ANY president is valid without the consent of the Legislature.
The executive branch of the U.S. government has the power to negotiate treaties with foreign nations. Specifically, the President negotiates treaties, but they must be ratified by a two-thirds majority in the Senate to become legally binding. This system ensures a check on the President's power by requiring Senate approval for international agreements.
He can and does meet with foreign heads of state and negotiate treaties and other accords or agreements. However, any treaties he makes are not binding unless the Senate ratifies them.
The Senate has the right of ratification.
The Executive Branch makes the Treaty, this branch includes the President, the US Senate ratifies the Treaty by a two thirds majority. Only then is it effective.
In the United States, that power is vested in the President, but the treaties must be approved by the Senate. This is Article II, Section 2, Clause 2, of the Constitution.
