Over the weekend, 11 nations reached a final agreement in Atlanta on the Trans-Pacific Partnership (TPP), a wide-ranging deal that would expand corporate rights across member states to the detriment of worker rights, the environment and public health.

But the agreement between heads of states does not mean that the TPP is a done deal. All of these countries must now secure legislative approval.

Although the U.S. Congress voted to give President Obama “fast-track authority,” meaning the body gave up its power to amend the agreement and must simply vote yes or no, that is not a guarantee that the TPP will get the votes it needs.

Standing in the way are presidential politics. For one, Democratic candidate Bernie Sanders has long opposed the agreement, and he made clear that he continues to oppose it in a statement today, saying he was “disappointed but not surprised by the decision to move forward on the disastrous Trans-Pacific Partnership trade agreement that will hurt consumers and cost American jobs.

“Wall Street and other big corporations have won again,” Sanders continued. “It is time for the rest of us to stop letting multi-national corporations rig the system to pad their profits at our expense.”
