It's customary for the Administration to get the approval of the Congressional leadership before submitting an agreement negotiated under trade promotion authority (fast track) for ratification. Bush Administration leaders are debating whether or not to submit the pending trade agreements with Columbia, Panama, and Korea without that approval if necessary (Will the Bush Administration "Force" Congressional Action?, The Custom-House, January 12, 2008)
The Columbia deal is widely expected to come up first, and will be controversial because of human rights issues. Doug Palmer reports on concerns that, if the Administration pushes ahead on Columbia, without getting the signal from the Congressional leadership, the fast track concept may end up wrecked for all time, as a trade policy tool: Colombia trade fight could cripple US fast track (Doug Palmer, Reuters, via the Guardian, January 18, 2008).
