This report is by Senator Tom Coburn, Ranking Member, Committee on Homeland Security and Governmental Affairs, U.S. Sentate, 113th Congress. From the Executive Summary: "The Department of Homeland Security (DHS) is the result of the largest reorganization of government in more than half a century. The reorganization included the consolidation of components and offices from 22 different agencies to create a unified department focusing on homeland security. In 2015, DHS will employ roughly 240,000 people, and spend nearly $61 billion. It is the third largest cabinet agency in government. Since 2003, the Department has spent approximately $544 billion on its programs. Congress has assigned to DHS some of the federal government's most important responsibilities related to securing the nation, including terrorism prevention and protective security, transportation security, border security, immigration enforcement, cybersecurity, and disaster recovery. This report presents the findings of Senator Tom Coburn's oversight of DHS. Since 2005, Dr. Coburn has been a member of the Senate Homeland Security and Governmental Affairs Committee. He served as the Committee's ranking member during the 113th Congress. The report is based on a review of evidence and information obtained from the department, audits and investigations conducted by watchdogs, committee hearings, and open source reporting. Where evidence was lacking, the report suggests opportunities for additional oversight by Congress and other watchdogs."
