Congress has once again abrogated it's duties to the executive branch and agreed to "fast track" this, meaning they don't get any input for 7 years beyond an up or down vote.
Sounds like the kleptocracy in fine form to me but I'm not expert in such things.
Aside from select members of the Administration, the only people with full access to the working documents on the TPP negotiations are the members of the United States Trade Representative’s (USTR) trade advisory system, including the 18-member Industry Trade Advisory Committee on Intellectual Property Rights (ITAC-15). Members of ITAC-15 include representatives from businesses and industry groups like the Recording Industry Association of America, Verizon, and Pharmaceutical Research and Manufacturers of America; no public-interest groups, academics, or other non-industry experts serve on the committee.
The industry trade advisory system was created by Congress, and membership is partly based on recommendations made from senators and representatives. The organizations represented on ITAC-15 include several top political spenders, who combined have given millions of dollars to members of Congress in recent years.
