The TPA portion of the bill would renew the on-again-off again "fast track authority" that Congress has often awarded to the president over the past several decades. The essential features of TPA are: (1) Congress unconstitutionally delegates its constitutional authority "to regulate commerce with foreign nations" to the Executive Branch; and (2) Congress dramatically increases the probability of approval of foreign trade agreements by restricting itself to voting up or down by simple majority on the agreements, as negotiated and submitted by the president, with no ability to amend the agreements and with no possibility of filibusters in the Senate.
TPA would facilitate the subordination of the national independence of the United States to regional trading blocs.
