From the William C. Blakley Law Library:
“The United States often enters into agreements with other countries. Two types of agreements are treaties and executive agreements. The United States Constitution art. 2, § 2 dictates that treaties are international agreements that have received the advice and consent of two-thirds of the Senate and have been ratified by the President. There are two types of treaties. Bilateral treaties are agreements made by two countries. Multilateral treaties are agreements made by three or more countries. As chief executive of the United States, the President has the authority to create international agreements with other nations without Senate approval. These international agreements are called executive agreements.”
Nothing there that says Obama and Kerry cannot get advice from the Senate. And those two clowns sure do need adult supervision.
Far be it for me to criticize Mr. Blakley, but I cannot find a basis for that "authority" in our nation's Constitution.
