This week, the Senate will vote on whether to grant Obama fast track" authority to negotiate the TPP agreement, which involves a dozen countries around the Pacific. [Senator Elizabeth] Warren has previously claimed that the TPP's controversial Investor-State Dispute Settlement provision, or ISDS, could undermine or chill public interest regulations in the U.S. and other participating countries, and could even undercut Dodd Frank financial reform, one of Obama's signature achievements. Obama has strongly rejected Warren's arguments in [an] interview with Yahoo and elsewhere. "The president said ... that he's confident that when people read the agreement for themselves, that they'll see it's a great deal. But the president won't actually let people read the agreement for themselves, [and] has committed only to letting the public see this deal after Congress votes to authorize fast track. At that point it will be impossible for us to amend the agreement or to block any part of it without tanking the whole TPP." Senator Warren went into more detail: "Congress will decide whether to give the President Fast Track authority. That authority would prevent Congress from amending trade deals and reduce its ability to block trade deals ... for ANY trade deal cut by ANY president over the next six years. Big banks on both sides of the Atlantic are gearing up to use that agreement to water down financial regulations. A six-year Fast Track bill is the missing link they need to make that happen."
