The latest from White House spokesperson Josh Earnest:

“We continue to be very confident in the legal case we have to make,” Earnest told reporters. “What’s also true is that if the Supreme Court were to throw the health care system in this country into utter chaos, there would be no easy solution for solving that problem because it would likely require an act of Congress in order to address that situation.”

If the Supreme Court invalidates the IRS Rule, it is Congress that created the mess, by writing the statute the way they did. Though, I doubt the White House would view any decision invalidating the IRS Rule as legitimate, and would continue to blame the Justices.
