From the article:

Under TPA, Congress lays out three basic requirements for the administration. First, it must pursue nearly 150 specific negotiating objectives, like beefing up protections for U.S. intellectual property or eliminating kickbacks for government-owned firms. Second, the administration must consult regularly with Congress and meet high transparency standards.

And third, before anything becomes law, Congress gets the final say. The Constitution vests all legislative power in Congress. So TPA makes it clear that Congress—and only Congress—can change U.S. law. If the administration meets all the requirements, Congress will give the agreement an up-or-down vote. But if the administration fails, Congress can hit the brakes, cancel the vote and stop the agreement.

Trade-promotion authority will hold the administration accountable both to Congress and to the American people. Under TPA, any member of Congress will be able to read the negotiating text. Any member will be able to get a briefing from the U.S. trade representative’s office on the status of the negotiations—at any time. Any member will get to be a part of negotiating rounds. And most important, TPA will require the administration to post the full text of the agreement at least 60 days before completing the deal, so the American people can read it themselves.

The stakes are high, because if you’re not moving forward in trade negotiations, you’re falling behind. In the first 10 years of this century, the countries of East Asia negotiated 48 trade agreements. The U.S., on the other hand, negotiated just two in that region. As a result, America’s share of East Asia’s imports fell by 42%. Every top U.S. competitor did better—every one of them.

That and all that you included in your post means next to nothing since Congress only has an up or down vote with no opportunity to amend the agreement. They set it up that way so they can pretend that the overall agreement is so important and will be so great for the US that they couldn't possibly reject the entire agreement negotiated with umpteen nations because of a few little troublesome details.

They deliberately shut Congress and the people out of the process to avoid objections to details they know would be rejected it presented individually.

Believe none of it. It’s all kabuki theater, and it breaks my heart that Cruz is actually supporting it.

Didn't they promise this on Obamacare and then didn't do it?
