In 2012, critics such as Public Citizen's Global Trade Watch, a consumer advocacy group, called for more open negotiations in regard to the agreement. U.S. Trade Representative Ron Kirk responded that he believes the Office of the United States Trade Representative (USTR) conducted "the most engaged and transparent process as we possibly could", but that "some measure of discretion and confidentiality" are needed "to preserve negotiating strength and to encourage our partners to be willing to put issues on the table they may not otherwise."
