While the Senate considers a 700-mile fence along the Mexican border, the House is going underground, working on legislation to crack down on those who would smuggle illegal immigrants and drugs through cross-border tunnels. The tunnel bill was one of three border security measures the House was taking up Thursday Sept. 21, 2006 as part of the pre-election effort by congressional Republicans to show they are serious about stopping the flow of illegal immigrants across the nation's porous borders.
