Totally false. Catos Bill Watson and I explained this at length in The Federalist last year, but heres former Attorney General Ed Meese to reinforce our conclusions:
The TPA legislation is clearly constitutional because Congress retains its authority to approve or reject all future trade agreements. It might be unconstitutional if Congress tried to delegate its authority to approve the final deal–but that is not at issue. Congress may always kill any future international agreement by withholding its final approval. The only difference under TPA is that Congress consents not to kill the agreement by amendment (i.e., the death by a thousand cuts). The Constitution grants each house of Congress the authority to establish its own rules of procedure, and it makes perfect sense for Congress to limit itself to straight up-or-down votes on certain resolutions, such as base closures and its own adjournment motions.
Constitutional law professor John O. McGinnis also recently reviewed TPA and concluded that TPA simply permits Congress under its ordinary procedures to commit to a future majority vote of Congress to vote up or down on an agreement that the President has negotiated. Representative democracy is thus served by the later vote on an agreement whose text is known. And then theres the U.S. Supreme Court in the 1890 case of Field v. Clark approving the constitutionality of an analogous lawthe McKinley Tariff Act of 1890, which granted the president even more authority than TPA. It was no big deal.
Finally, its important to reiterate that, contrary to some claims, FTAs are not treaties (which are typically self-executing, require two-thirds approval by the Senate, and have the force of law upon ratification). They are congressional-executive agreements that, even after being signed by the president, have absolutely no legal force until they are converted into implementing legislation (which would amend current law), passed by Congress, and signed into law by the president. Such agreements have for decades been used by the United States for many different issues, including trade liberalization, and U.S. courts have repeatedly rejected constitutional challenges thereto.
In short, a constitutional argument against TPA requires you to reject over a century of precedent, the repeated rulings of U.S. courts, and the opinions of even the strictest of constitutional scholars.
Myth 2: Abortion is unconstitutional
I don't care what Meese or some courts say. Trade deals are treaties negotiated between nations. They should be subject to the same ratification process.
But the argument that "none would ever pass" or "its too hard" or "amendments would be death by a thousand cuts"
This is nonsense.
Our Founders wanted such deals to be difficult to ratify or everyone would be bribed into doing them....which is exactly what is happening.
I favor free trade. But we would not have free trade with China if it had to be ratified by a 2/3 majority vote because they do not play fair.
TPA is just an end run to get things done quickly before anyone realizes the crappy deal.
I hope you know the basis for our talks with Iran are based on trade as well?
