Summary of Article: United States and Mexico work together in order to put an end to drug trafficking. The relationship between Mexican and American officers has been strained by the recent background checks. American personnel perform regular mandated polygraph test to ensure that there isn't corruption within Mexican security. However, the president of Mexico, Enrique Pena Neito doesn't agree with the policy that was implemented by United States agents, and he believes that it's in their right to deny the U.S. these privileges. In response, President Obama has agree to converse with President Nieto to discuss possible boarder security reformation.
