The remaining $15 billion would cover technology, personnel and readiness, the document says.

Titled "Critical CBP Requirements to Improve Border Security," the document says CBP has identified what a 2,026-mile border wall system would entail --comprising about 864 miles of new wall and about 1,163 miles of replacement or secondary wall -- even as administration officials and their allies insist they are not pursuing a wall "from sea to shining sea," as Homeland Security Secretary Kirstjen Nielsen and her predecessor John Kelly have testified to Congress.
