This legislation, known as the REPORT Act, requires the Secretary of Homeland Security, the Attorney General, the Director of the Federal Bureau of Investigation, and the head of the National Counterterrorism Center to submit joint reports to Congress and make them publicly available after an act of terrorism occurs in the United States. These unclassified reports, which may include a classified annex, must be submitted within one year of the primary investigation's completion to specific congressional committees. Each report must include a statement of the incident's facts, identify any homeland or national security gaps , and provide recommendations for improvements, including potential changes in law enforcement practices or laws, to prevent future acts of terrorism. While information that could jeopardize an ongoing investigation may be withheld, the agencies must notify Congress of such a determination, and the reporting requirement for this section will terminate five years after the Act's enactment.
