They did not end negotiations with Colombia; they completed negotiations with Colombia. They are having a debate in the United States as to whether they will ratify the agreement. Some are criticizing it for the same reasons that some in Canada would criticize trade with Colombia. My guess is that they will, at the end of the day, ratify the agreement with Colombia.
I heard a senior official from the State Department, when I was in Miami yesterday, speak very positively on the role of the U.S.-Colombia free trade agreement in terms of helping Colombia out of the kind of cycle of violence and crime they have been trapped in for so long. I think you're going to see the Americans eventually ratify that agreement.
