The TPA had the effect of delegating congressional power to the executive branch with limitations. Fast track agreements are enacted as "congressional-executive agreements" (CEAs), which are negotiated for by the executive branch following set guidelines from Congress, and are approved by a majority in both chambers of Congress. Without the TPA legislation, the President's power to negotiate trade deals is restricted by Article II, Section 2, of the U.S. Constitution which states that: "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."
