S. 848 — REPORT Act

This section establishes a duty for the Secretary of Homeland Security, Attorney General, Director of the Federal Bureau of Investigation (FBI), and—as appropriate—the Director of the National Counterterrorism Center (NCTC) to submit to specified congressional committees (i.e., Senate and House Homeland Security, Judiciary, and Intelligence committees) an unclassified report (possibly with a classified annex) on each act of terrorism occurring in the United States, within one year after the primary investigating agency's investigation concludes, and to post the report on a publicly accessible website. Each report must describe known facts, identify homeland or national security gaps to prevent similar acts, and recommend measures to improve security—including potential changes to law enforcement practices or laws—with reports combinable into quarterly submissions and available to any Member of Congress upon request. The section authorizes withholding information that could jeopardize ongoing investigations or prosecutions (with committee notification), sunsets five years after enactment, and clarifies that it does not grant NCTC prosecutorial or investigatory authority.
