Brownfield told Spanish press agency Efe his country “owes” Colombia, after the rescue of U.S. military contract workers Keith Stansell, Marc Gonsalves and Tom Howes last week.”My country is in debt with Colombia for the liberation of 15 hostages, especially the Americans. My congress should speed up the ratification of the North American Free Trade Agreement, after what Colombia has shown,” the ambassador said.U.S. president George W Bush repeatedly asked Congress to approve the law. The Democratic majority of the House however, blocked the vote until after the U.S. presidential elections in November, claiming Colombia should first improve it’s human rights situation.
