Border Security: Assessment of the Department of Homeland Security's Border Security Improvement Plan [open pdf - 1MB]
From the Document: "Within the Department of Homeland Security (DHS), U.S. Customs and Border Protection (CBP) is the lead law enforcement agency responsible for border security. CBP manages approximately 7,000 miles of land border and 95,000 miles of shoreline. CBP is also responsible for managing the flow of trade and travel through 328 land, air, and maritime ports of entry. Several offices within CBP help carry out this mission, including the U.S. Border Patrol, Air and Marine Operations, and Office of Field Operations. The DHS Appropriations Act, 2018, required the Secretary of Homeland Security to concurrently submit to the House and Senate Appropriations Committees and Comptroller General a riskbased plan for improving security along the borders of the United States, including how CBP intends to use personnel, fencing, other forms of tactical infrastructure, and technology. The act requires us to evaluate this plan and report to the appropriations committees on the strengths and weaknesses of the plan not later than 120 days after receiving it."
