On January 20, 2025, President Trump issued a memorandum entitled "Regulatory Freeze Pending Review." The Order requires that (1) no agency propose or issue any rule without review and approval of an agency head appointed or designated by President Trump, and (2) any rule submitted to the Federal Register but not yet published be withdrawn pending review. The Order also suggests that agencies postpone the effective date of rules already issued by 60 days. The Order makes an exception for rules that the Office of Management and Budget “necessary to address emergency situations or other urgent circumstances, including rules subject to statutory or judicial deadlines that require prompt action.”
To explore recent regulations that may be subject to the suggested 60-day postponement of effective date, see the Climate Regulation Database.
