Welcome to Supreme Court Brief and the second day of the February argument session. The justices could issue opinions this morning—we’ll stay in touch.

And the justices will see a new Justice department face at the lectern tomorrow when Deputy Attorney General Jeffrey Rosen makes his high court debut.
