Senator Chris Murphy, Chairman of the U.S. Senate Appropriations Subcommittee on Homeland Security, on Wednesday spoke on the U.S. Senate floor to highlight the inextricable link between the flow of illegal guns from the U.S. into Mexico and the flow of fentanyl from Mexico into the U.S. largely by American citizens. Murphy argued that the United States must do more to combat the trafficking of guns into Mexico in order to disrupt the cartel violence that fuels the fentanyl crisis at home.
