The initial flurry of regulatory actions by the Biden administration has been to withdraw regulations that were not finalized by the Trump administration.
The White House has sent forward for review by the Office of Management and Budget (OMB) notices or regulatory actions to require the wearing of masks on public transportation and in stations, ports or similar transportation hubs, a temporary halt in residential evictions — both from Health and Human Services — and a delay in the effective date of the Trump administration's final rule limiting regulatory science that was issued by EPA. A federal judge had also put a halt to the EPA rule.
The new administration has embarked on a broad regulatory review of actions by the Trump administration which has resulted in some regulations or actions being either halted or suspended by several agencies.
