The date is pretty suspect though.

Not really

Yes, it is. It’s not common to enact laws on the day before one leaves office. Pardons, sure.

It’s clearly an attempt to ram it through before the administration changes. Even a year ago they knew there was a good chance of that.

How is it rammed through?

Do you think it’s just coincidence that the date was the last day of a presidential term? Can you think of other controversial laws that did that?
