173. 151 House Dems Telling President They Will Not Support Outdated Fast Track for TPP

We write to express our serious concern with the ongoing negotiations over the Trans-Pacific Partnership (TPP) Free Trade Agreement (FTA), a potential agreement of tremendous consequence for our country. Specifically, we remain deeply troubled by the continued lack of adequate congressional consultation in many areas of the proposed pact that deeply implicates Congress’ constitutional and domestic policy authorities.

For some time, members of Congress have urged your administration to engage in broader and deeper consultations with members of the full range of committees of Congress whose jurisdiction touches on the numerous issues being negotiated. Many have raised concerns relating to reports about the agreement’s proposed content.

And my Senator, Ron Wyden, Democrat
WASHINGTON -- Sen. Ron Wyden (D-Ore.) introduced legislation late Wednesday to protest the Obama administration's refusal to share information about controversial trade negotiations with the senator.

The administration's blockade against Wyden, who chairs a subcommittee on international trade, conflicts with its prior statements to the press, and raises concerns that President Barack Obama's administration is selectively icing out critics of the administration's trade strategy.

Wyden said that his office was locked out of information about a trade pact in the works known as the Trans-Pacific Partnership. The deal, which involves eight other Pacific nations, includes broad details on government contracting terms that would ban "Buy American" preferences for U.S. manufacturers, and intellectual property standards that would increase prescription drug prices abroad. Those positions have drawn criticism from American labor unions, domestic manufacturers and international public health advocates.
