"Securing U.S. borders is the responsibility of DHS, in collaboration with other federal, state, local, and tribal entities. Within DHS, CBP [Customs and Border Protection] is the lead agency for border security and is responsible for, among other things, keeping terrorists and their weapons, criminals and their contraband, and inadmissible aliens out of the country. In recent years, GAO [Government Accountability Office] has reported on a variety of DHS collaborative mechanisms and efforts to assess its use of border security resources. This statement addresses (1) DHS's efforts to implement collaborative mechanisms along the southwest border and (2) DHS's efforts to assess its use of resources and programs to secure the southwest border. This statement is based on GAO reports and testimonies issued from September 2013 through February 2017 that examined DHS efforts to enhance border security and assess the effectiveness of its border security operations. GAO's reports and testimonies incorporated information GAO obtained by examining DHS collaborative mechanisms , reviewing CBP policies and procedures for coordinating use of assets, analyzing DHS data related to enforcement program s, and interviewing relevant DHS officials."
