Expands the Committee on Foreign Investment in the United States (CFIUS) authority so it can review foreign purchases, leases, or concessions of U.S. real estate near military installations or military airspace, and requires broader congressional notification of those reviews. It also creates a pause on approvals for certain energy projects sited on land under CFIUS review: the Department of Defense must delay or report its national security analysis and the Department of Transportation cannot complete specified determinations until CFIUS and DoD finish their reviews, with a mandate to treat referred transactions as unacceptable national security risks if the President is involved.
