The US government is preparing to begin construction of more border walls and fencing in South Texas' Rio Grande Valley, likely on federally owned land set aside as wildlife refuge property.
Heavy construction equipment was expected to arrive starting Monday, US Customs and Border Protection said. A photo posted by the nonprofit National Butterfly Center shows an excavator parked next to its property.
Congress last March approved more than USD 600 million for 33 miles (53 kilometers) of new barriers in the Rio Grande Valley. While President Donald Trump and top Democrats remain in a standoff over Trump's demand for USD 5.7 billion in border wall funding, US Customs and Border Protection has pushed ahead with building what's already funded.
That construction was often described as fencing, and the government funding bill that included construction was supported by some Democrats in the House and Senate. CBP refers to what it plans to build as a "border wall system."
