Republican leaders, in tandem with Trump’s transition staff, are considering using a 2006 law signed by former President George W. Bush that authorized the construction of 700 miles-plus of “physical barrier” on the southern border. The law was never fully implemented and did not include a sunset provision, allowing Trump to pick up where Bush left off — with the help of new money from Congress. ...
The 2006 Secure Fence Act, included as part of a broader immigration reform package, originally called for 850 miles of double fencing along the nearly 2,000-mile southern border. Lawmakers amended the law in 2008 to reduce the length to a minimum of 700 miles, a change that also gave the secretary of Homeland Security discretion over what kind of “physical barrier” to construct.
Ultimately, only 36 miles of double-layer fencing was erected. U.S. Customs and Border Protection built roughly 350 miles of single-layer pedestrian fences, most which stand about 18 feet, and 300 miles of low-level vehicle barriers that any person could easily walk through, according to sources following the matter.
