Drug-related violence in Mexico has killed more than seven thousand people since the beginning of last year -- often with guns bought in the United States. The violence is now spreading over the border to American communities. This comes as American officials say Mexican organized crime groups are supplying drugs in a growing number of cities across the United States.

President Obama says the United States must reduce its demand for drugs and do its part to reduce the flow of guns and money to Mexico. Earlier this week, he used a law called the Foreign Narcotics Kingpin Designation Act to target three Mexican drug organizations. The action will let the Treasury Department block or seize any of their money within reach of United States laws.
