Senator Warren tells the President to put up or shut up

See this article. I really want to see the President respond to it. Senators Warren and Brown wrote a letter asking the President to make the full details of the TPP available so that we the people can have a dialog with our representatives before they vote on it. Seems reasonable enough. Even George W. Bush did so on a major trade deal with Latin America? Plus the fact on who supports the TPP and who doesn't says a lot. For it: Multi-national corporations and the Chamber of Commerce. Against it: organized labor, environmentalists and even some in the Tea Party. The thing has been written by the big corps for their own profit. And we're supposed to believe they give one shit about labor or the environment with their proven track record? Seriously Mr. President?
