Donald Trump’s administration is doing an extraordinary amount of "midnight rule-making” — issuing regulations at the very end of the president’s four-year term. This will cause real trouble for the Joe Biden administration, which will have to try to unwind a lot of it.

Trump’s Office of Information and Regulatory Affairs has hundreds of regulations under review, suggesting that there might well be a last-minute tsunami.

Some of the last-minute regulations are genuinely terrible, such as new restrictions on granting asylum to people threatened with gang or gender violence. But others are more complicated, in the sense that they are likely to produce disparate reactions among Biden’s supporters — and potentially reveal significant fissures among progressives.
