The New York Times has just reported that the Senate Commerce Committee held a closed-door, unannounced markup earlier today. During the markup, the Committee unanimously approved both John Holdren and Jane Lubchenco, and both nominations are expected to move to the floor.
According to the Times, both John Rockefeller (the Committee Chair) and Kay Bailey Hutchison (the ranking Republican) say that all holds that they know of have been released, and that the nominees should be confirmed sometime this week.
I'll keep an eye on this story, and let you know if there are any changes. I'd like to thank everyone who took the time to contact members of the Senate, and everyone who tolerated several days of my near monomaniacal focus on this issue.
