Where's Cass?

We reported back in January that the president planned to nominate Harvard professor Cass Sunstein to head OMB’s Office of Information and Regulatory Affairs.

So where’s his nomination?

The White House’s nominations list doesn’t mention Sunstein. (In fact, if you search for him on the White House Web site, you won’t get any results.) The Senate Homeland Security and Governmental Affairs committee tells me it hasn’t heard a word about Sunstein’s nomination. And the White House hasn’t responded to a request for comment.
