US Vice President Mike Pence blasted "weak" and "ineffective" immigration laws Monday during a trip to the border with Mexico, as a caravan of immigrants two hours to the west prepared to claim asylum in America.
Pence's remarks came as he toured a construction site for a barrier in the Californian border town of Calexico, 120 miles (200 kilometers) east of the San Diego-Tijuana crossing where the group of at least 150 people has amassed.
