This legislation, titled the Critical Infrastructure Security Act, aims to strengthen national security by amending the Defense Production Act of 1950. It expands the authority of the Committee on Foreign Investment in the United States (CFIUS) to scrutinize foreign real estate transactions involving sensitive U.S. government facilities and critical infrastructure. Specifically, the bill modifies the definition of "covered transactions" to include facilities or property of the intelligence community and National Laboratories , as well as properties sensitive for reasons relating to critical infrastructure , including drinking water. It mandates that each CFIUS member annually review a list of their agency's sensitive facilities and property, submitting a report with recommended updates to the chairperson. Furthermore, the bill requires CFIUS to include a list of all notices, declarations, reviews, and investigations related to these sensitive government facilities and critical infrastructure in its annual report to Congress, and provides for classified briefings to Members of Congress upon request regarding these sensitive lists.
