How Can Obama Deny Mexican Border Problems When U.S. Agents Just Found Longest Drug Tunnel Ever Despite Obamas opposition to build up and defend the Mexican border, facts continued to underline just how critical this problem is. The latest evidence of this is a half-mile tunnel that was recently discovered in San Diego. This is the longest drug tunnel that has been discovered by US Border Agents. The drug seizure from busting the operation was also record-breaking. This is the largest cocaine seizure ever associated with a tunnel, Laura Duffy, U.S. Attorney for the Southern District of California told reports. 11,000 pounds of marijuana was also discovered. The operation may have never been discovered if it werent for a Border Agent who was suspicious of what he observed, particularly the company hiding the tunnel entrance. What do you think of this bust?
