While discussing the ongoing drug war in Mexico with Homeland Security Secretary Janet Napolitano on Thursday’s CBS Early Show, co-host Maggie Rodriguez wondered: "President Obama will meet with the Mexican president today, who has said that the money, the guns, and the appetite for drugs that fuel this war come from our country. My question is, how much blame do we accept?...Is one of the other things we can do reinstate the assault weapons ban in this country? Because President Calderon has said that ever since it expired, violence there has escalated." In an earlier report on the issue, correspondent Bill Plante explained: "Mexican authorities are often out-gunned by the gangs. Military-grade arms, including grenades and machine guns, are easily purchased in the U.S. and smuggled into Mexico. Just as the drugs are easily moved north in response to heavy demand in the U.S...President Obama will promise today to step up efforts to stop the flow of weapons from the U.S. down into Mexico." Earlier media reports claimed 90% of guns involved in the Mexican drug war came from the U.S., a statistic which was later proven false by Fox News’s William La Jeunesse and Maxim Lott.
