I'd ask for a citation of what Biden/Biden's admin actually did, but the Trump folks have been so busy disappearing things that the policy that I think you're referring to is now gone from the WhiteHouse.gov site and doesn't seem to be available via Internet Archive either.
Once again, in harmony, and louder for the people in the back: the both-sidesism is utterly misguided, plays into the Trump camp's hands, and just entirely fails to recognize just how not-normal and dangerous things are right now and they are just getting worse by the day.
