This letter from Elizabeth Warren and Sherrod Brown sets the perfect tone for the debate on the TPP. It is respectful while at the same time not backing down an inch in their criticisms of the process so far. It lays out the case on the whole secrecy issue, and while being respectful of the President themselves ask for the same respectfulness from him. Having worked inside a White House, been involved in behind closed doors negotiations, and been aware of the difference between classified and non-classified government material, I want to add this point in support of Warren's and Brown's request for opening these documents up the public: the proper role of making documents classified is in the national security interests of the country -- in other words, military intelligence, information on terrorist threats, information on security vulnerabilities for our country, information from diplomatic discussions on threats to the stability of other countries.
