Hello, I'm having a slow day, so I thought I'd do some education to distract everyone yelling at each other about the Campus protests.
For those that don't know, every major rule or regulation (but not Executive Order) is potentially subject to the Congressional Review Act.
In short: the CRA allows Congress to overturn any rule by law, in an expedited and filibuster proof procedure. It must be signed into law by the President, and if successful, prevents future administration's from substantially similar efforts. There is a time limit to when it can be used. This year that day is probably May 22.
For simplicities sake, this year, if the Biden Administration wants to prevent the next Congress and future President Trump from overturning a rule or regulation, the rule needs to be finalized and printed before Memorial Day.
This is why you are seeing daily rules about health, labor, environment being released. In 2015, the Obama administration was lazy about the CRA and lost over a dozen rules because they thought Hilary was going to win.
