Editor's Note: Authorities have uncovered an underground tunnel between Tijuana, Mexico and San Diego, California. In 2006, Anderson reported on the drug tunnels under the U.S. border with Mexico. Watch his report here. We'll broadcast live from this new tunnel on Thursday at 10 p.m. ET.
Anderson Cooper goes beyond the headlines to tell stories from many points of view, so you can make up your own mind about the news. Tune in weeknights at 8 and 10 ET on CNN.
