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. It manages approximately 7,000 miles of land border and 95,000 miles of shoreline. CBP is also responsible for facilitating legitimate 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 (Border Patrol), Air and Marine Operations, and Office of Field Operations. The DHS Appropriations Act, 2017, required the Secretary of Homeland Security to submit a risk-based plan for improving U.S. border security--referred to as the Border Security Improvement Plan--to the House and Senate Appropriations Committees. [...] This report addresses the extent to which the 'Fiscal Year 2019-2020 Border Security Improvement Plan' (the 2019-2020 plan) includes the elements required by the DHS Appropriations Act, 2018, as referenced by the 2019 and 2020 appropriations acts."
