You can get live blog coverage of the U.S. Supreme Court action this morning if you go here. No guarantee D.C. v. Heller will be released. It could be later this week instead.
Update: Nothing on D.C. v. Heller today. Maybe later this week. Additional hints from the above link:
Tom Goldstein – The only opinion remaining from the March sitting is Heller. The only Justice without a majority opinion from that sitting is Justice Scalia.
Tom Goldstein – The Court has announced that it will release opinions against at 10am Wednesday. Because seven opinions remain, it will almost certainly have one additional day. Based on past practice, that day likely will be Thursday.
