Two Senate Democrats have sponsored a bill demanding the White House reveal the terms of the Trans-Pacific Partnership (TPP) to the public at least two months before Congress could give President Obama fast-track authority.

Joe Manchin of West Virginia joined Elizabeth Warren of Massachusetts in proposing the two-page Trade Transparency Act, reports The Hill. If adopted, the bill would require the White House release the “scrubbed bracketed text of any trade agreement” no less than 60 days prior to a vote in Congress on fast-tracking the treaty.
