Senator Elizabeth Warren (D-MA) offered an amendment to H.R. 1314, the Trade Act of 2015, which would prohibit the application of “fast track” authority, which allows for expedited congressional approval of international trade deals for any agreement that includes a provision allowing investor-state dispute settlement (ISDS). Investor-state dispute settlement is a mechanism that allows foreign corporations to challenge government policies and actions that companies claim harm their investments or profits, and these challenges take place in front of private trade tribunals. The use of ISDS has increased rapidly in recent years, and many of these cases have involved challenges to environment and clean energy policies. On May 22, the Senate rejected the Warren amendment by a vote of 39-60 (Senate roll call vote 188). YES IS THE PRO-ENVIRONMENT VOTE.
