This report discusses the legal background associated with the sunset of various provisions of the USA PATRIOT Act and of subsequent related legislation.

Congress enacted the USA PATRIOT Act soon after the 9/11 terrorist attacks. The most controversial sections of the Act facilitate the federal government's collection of more information, from a greater number of sources, than had previously been authorized in criminal or foreign intelligence investigations. The Foreign Intelligence Surveillance Act (FISA), the Electronic Communications Privacy Act (ECPA), and the national security letter (NSL) statutes were all bolstered. With the changes came greater access to records showing an individual's spending and communication patterns as well as increased authority to intercept e-mail and telephone conversations and to search homes and businesses. In some cases, evidentiary standards required to obtain court approval for the collection of information were lowered. Other approaches included expanding the scope of information subject to search, adding flexibility to the methods by which information could be collected, and broadening the purposes for which information may be sought. Some perceived the changes as necessary to unearth terrorist cells and update investigative authorities to respond to the new technologies and characteristics of ever-shifting threats. Others argued that authorities granted by the USA PATRIOT Act and subsequent measures could unnecessarily undermine constitutional rights over time. In response to such concerns, sunset provisions were established for many of the changes.

The official report that has shaped the international debate about NSA surveillance "We cannot discount the risk, in light of the lessons of our own history, that at some point in the future, high-level government officials will decide that this massive database of extraordinarily sensitive private information is there for the plucking. Americans must never make the mistake of wholly 'trusting' our public officials."—The NSA Report This is the official report that is helping shape the international debate about the unprecedented surveillance activities of the National Security Agency. Commissioned by President Obama following disclosures by former NSA contractor Edward J. Snowden, and written by a preeminent group of intelligence and legal experts, the report examines the extent of NSA programs and calls for dozens of urgent and practical reforms. The result is a blueprint showing how the government can reaffirm its commitment to privacy and civil liberties—without compromising national security.
