All we hear from the media is that no information is available to the public. And did they leak any information about NAFTA or GATT? (General Agreements on Tariffs and Trade).
They did release info on the TPP.

NAFTA was long before there was a Wikileaks.
GATT and NAFTA were enacted in 1994. Wikileaks did not exist until 2006. See the previous poster's contribution for what Wikileaks HAS provided about TPP.
They released a draft on the 15th of January 2014, which is linked above.
It was leaked but the mainstream media will black that out as much as it can.
Only evil is done in secret. All you need to know is that they didn't want you to know.
