This legislation, titled the "Safeguarding US Rulemaking Act," seeks to amend the Administrative Procedure Act to limit participation in federal agency rulemaking. Its primary goal is to prevent foreign governments designated as adversaries, along with their nationals and entities, from submitting public comments or petitions to U.S. agencies during the rulemaking process. The bill specifically modifies Section 553 of title 5, United States Code, by adding a new subsection (f). This new provision would render any foreign government determined by the Secretary of Commerce to be a foreign adversary , or any national or entity incorporated in such a government, ineligible to participate. The intent is to protect the integrity of U.S. regulatory processes from undue influence by hostile foreign actors.
