Shortly after President Biden took office, his Chief of Staff Ronald Klain signed a "Regulatory Freeze" memo directing federal agencies to:
1) Refrain from issue any new rule until approved by a Biden-appointee;
2) Withdraw any rules that have been sent to the Federal Register for publication but have not yet been published; and
3) For rules that have been published, but not yet gone into effect, “consider” postponing the effective date for 60 days and to provide a public comment
period for an additional 30 days to allow comments as to whether the rule
should be reconsidered or revoked.
