The U.S. Senate Thursday sent a $600 million bill adding agents and equipment along the U.S.-Mexican border to U.S. President Barack Obama for his signature. Obama, who planned to sign the bill Friday, said the law would protect border states beset by undocumented immigrants and illegal-drug traffickers. It would "also strengthen our partnership with Mexico in targeting the gangs and criminal organizations that operate on both sides of our shared border," Obama said in a statement. The bill's chief sponsor, Sen. Charles E. Schumer, D-N.Y., said the measure, which was already approved by the U.S. House of Representatives, would give Obama and Homeland Security Secretary Janet Napolitano "the boots on the ground and the resources necessary to combat the crime and violence." The bill would fund 1,000 new U.S. Border Patrol agents, 250 additional U.S. Immigration and Customs Enforcement agents and 250 more U.S. Customs and Border Protection officers. It would provide money for new communications equipment and improve the use of unmanned surveillance drones, the United Press International (UPI) reported.
