Largest yet: $1.3 billion contract awarded for border wall

Trump has promised to build 450 miles of wall along the border with Mexico by the end of the year. So far, the government has awarded millions of dollars in contracts for construction of 30-foot-tall barriers, along with new lighting, technology, and infrastructure. The Trump administration says it has already built 187 miles of wall. Some of it is new, but most is replacing old, much shorter barriers that officials say were not sufficient.
