And the news keeps coming.
Moments after learning that Donald Verrilli had been sworn in as Solicitor General, it now appears that Acting Solicitor General Neal Katyal has submitted his letter of resignation, effective at the end of the current Supreme Court term (presumably the end of June). According to Tony Mauro in this story, Katyal will be going into private practice in D.C. rather than back to Georgetown.
This just cements the supposition that Verrilli will appear for the United States in the upcoming ACA arguments, at least the important ones (which may well exclude those in the Third and Ninth Circuits).
