How could he have voted for rhe Corker Bill to abrogate the constitutional 2/3 Senate approval of ANY TREATY!!? What the hell was he thinking?
Actually this isn’t a Treaty. it’s an Agreement. It is no more than just another “trade agreement”.
What qualifies as a “treaty” for purposes of the Constitution is fairly narrow. A “Treaty” actually gives the Executive MUCH more authority to act outside the scope of Congress where an Agreement is more restrictive.
11 Fam 721.2 vies the analysis. There is also quite a bit of material on the subject but there is no doubt that this is not a treaty.
If any are at all interested, this link gets you started on the issue:
