What’s going to happen with House v. Burwell?

I’m getting a lot of head-scratching questions about the lawsuit, which is now pending at the D.C. Circuit. Let me see if I can help.

As I see it, there are two distinct questions in play:

1. Does President Trump want to stop making cost-sharing payments on Day One, leading to the immediate collapse of the individual insurance market in many states? Or does he want to keep making the payments during a transition period?
2. What approach will the Trump administration take to the litigation?
