From the Document: "On a typical day in fiscal year 2019, over 1.1 million passengers and pedestrians and over 78,000 truck, rail, and sea containers carrying goods worth approximately $7.3 billion entered the United States through 328 U.S. land, sea, and air ports of entry (POE), according to U.S. Customs and Border Protection (CBP). Within the Department of Homeland Security (DHS), CBP is the lead federal agency charged with a dual mission of keeping terrorists and their weapons, criminals and their contraband, and inadmissible aliens out of the country while facilitating the flow of legitimate international travel and trade through the nation's POEs. CBP's Office of Field Operations is responsible for conducting passenger and cargo processing activities related to security, trade, immigration, and agricultural inspection at the nation's POEs. [...] We conducted this performance audit from September 2019 to January 2020, in accordance with generally accepted government auditing standards. Those standards require that we plan and perform the audit to obtain sufficient, appropriate evidence to provide a reasonable basis for our findings and conclusions based on our audit objectives. We believe that the evidence obtained provides a reasonable basis for our findings and conclusions based on our audit objectives."
