Acting SG Clement to argue Booker and Fanfan

As noted in this post by the folks at the SCOTUS Blog, Acting Solicitor General Paul Clement (background here) will be arguing for the United States in Booker and Fanfan. I believe this is a bit of news because Deputy Solicitor General Michael Dreeben is reputed to be the “point person” on these cases, and he argued on behalf of the United States as amici in Blakely.
