HIDALGO, TX – APRIL 10: A U.S. Border Patrol Agent inspects a load of marijuana seized from drug smugglers near the U.S.-Mexico border on April 10, 2013 in Hidalgo, Texas. The agents, guided by helicopter surveillance from the U.S. Office of Air and Marine, waited more than four hours in hiding before seizing more than 900 pounds of the drug. The smugglers ran and escaped by swimming back across the Rio Grande River into Mexico. Border Patrol agents say they have also seen an additional surge in immigrant traffic since immigration reform negotiations began this year in Washington D.C. Proposed refoms could provide a path to citizenship for many of the estimated 11 million undocumented workers living in the United States. (Photo by John Moore/Getty Images)
