The government would be required to review when investment companies try to buy controlling stakes in major defense contractors to ensure national security isn't compromised. This review process would give officials a chance to examine whether foreign investors or other concerning parties could gain influence over companies that make weapons and military equipment for the U.S. armed forces.
