The memorandum formally re-establishes the Committee on National Security Systems (CNSS) under NSC staff coordination, designates the Director of the NSA as the National Manager for NSS, and rescinds earlier governing documents.

It sets forth governance, accountability structures, mandates cybersecurity requirements equivalent to or exceeding those for other Federal systems, and details implementation steps for harmonizing policies, incident reporting, and assessing cloud security.

This National Security Presidential Memorandum directs the comprehensive acceleration and responsible integration of Artificial Intelligence (AI) across the entire national security enterprise, including intelligence and warfighting domains.

The action is guided by four central policy pillars: Adoption of AI to enhance operational effectiveness, Adaptation by leveraging commercial and open-source technologies, Assurance that all AI is reliable and controllable, and Accountability to ensure AI use upholds U.S. civil liberties and the constitutional chain of command.

The memorandum mandates specific timelines for agency heads to update directives, establish governance frameworks, develop crucial computing infrastructure roadmaps, build AI talent reserves, and implement rigorous security testing methodologies, while also rescinding prior relevant guidance.

This Presidential Proclamation, issued by President Donald J. Trump on June 4, 2026, grants a full, complete, and unconditional pardon to Stephen E. Buyer, citing his distinguished and productive career in the United States Army Judge Advocate General's Corps and as a Member of the U.S. House of Representatives from Indiana.

The decision was made pursuant to Article II, Section 2 of the Constitution and followed the advice and recommendation of numerous endorsing individuals, including several members of Congress and former officials, with the Attorney General tasked to effectuate the issuance of the pardon certificate.

This Presidential Action mandates comprehensive reforms to U.S. customs enforcement, asserting that stronger measures are crucial for national security, foreign policy, and the economy.

The order directs the Secretary of Homeland Security to revise regulations within 180 days to enforce higher accountability standards for Importers of Record (IORs), including requiring tangible domestic assets or increased bonding, mandating detailed disclosure of ownership and supply chain data, and imposing stricter rules for foreign IORs, such as prohibiting their use of informal entry.

Furthermore, the action targets enhanced enforcement penalties for noncompliance, streamlined disposal of illegal imports, and established vetting procedures to ensure all parties involved in importing maintain 'good standing' with Customs and Border Protection (CBP).

This Presidential Action establishes a national policy focused on maintaining U.S. leadership in Artificial Intelligence (AI) by simultaneously encouraging innovation and strengthening national security against evolving AI-related threats.

The action directs various departments, including War, Homeland Security, and the Treasury, to immediately upgrade federal system cyber defenses, prioritize the defense of National Security Systems, and establish a voluntary information-sharing arrangement with AI developers regarding "covered frontier models" to assess potential risks before public release.

Furthermore, the Attorney General is tasked with prioritizing the criminal prosecution of individuals who misuse AI to illegally access or damage computer systems.

This Presidential Proclamation formally modifies the existing Section 232 tariff regimes imposed on imports of aluminum, steel, and copper, as established in prior proclamations, based on recommendations from the Secretary of Commerce regarding national security concerns and domestic economic impacts.

The modifications introduce a temporarily reduced 15 percent ad valorem duty for specific derivative products, including agricultural equipment and residential HVAC systems, while also extending coverage to products like aluminum lithographic plates and steel racks to prevent circumvention.

Furthermore, the proclamation lowers the threshold for a product to qualify as 'entirely' made of American metals from 95 percent to 85 percent to incentivize domestic sourcing.
