From NBC's Chuck Todd
NBC News has learned the long-rumored departure of White House Counsel Greg Craig will likely be made official tomorrow. Craig will be replaced by veteran Democratic Party campaign attorney Bob Bauer. This is the highest-level departure in the Obama White House this year.
In 2008, Bauer served as lead counsel for Obama's campaign.
Bauer is married to outgoing White House communications director Anita Dunn. Among the reasons for Dunn's decision to leave was so that both of them weren't working in the administration at the same time for their own family situation.
Craig has had a rocky tenure, beginning with the politically charged decision to shut down GITMO.
It is not yet known when this change will become official, but it likely will be before the end of the year.
