BS. Of course Congress is ceding its authority to the WH. And what about the American people? What kind of transparency and accountability do they have from their elected officials. The Constitution is being stood on its head. Congress can't even amend the legislation.
If, as promoters amazingly suggest, the President had more powers without fast-track, he would veto it. The authority granted in “Trade Promotion Authority” is authority transferred from Congress to the Executive and, ultimately, to international bureaucrats. The entire purpose of fast-track is for Congress to surrender its power to the Executive for six years. Legislative concessions include: control over the content of legislation, the power to fully consider that legislation on the floor, the power to keep debate open until Senate cloture is invoked, and the constitutional requirement that treaties receive a two-thirds vote. Legislation cannot even be amended.
So why does the WH need this authority?
The Senate can change any fast-tracked item as long as they get 60 votes.
