Plenty of movement around official Washington this week.

Sheila Nix, who was Vice President Biden’s campaign chief of staff, is the new chief of staff for Jill Biden. She replaces Cathy Russell, who last month was named the State Department’s ambassador at large for global women’s issues.

Elsewhere, David Sandalow, assistant secretary for policy and international affairs at the Energy Department, is leaving for the ivory tower. He will be the inaugural fellow at Columbia University’s new Center on Global Energy Policy.

And regime change is also underway at State: Assistant Secretary Andrew Shapiro — one of the holdovers from former secretary of state Hillary Clinton’s circle — is leaving soon. Which means Secretary of State Kerry will have a chance to bring in one of his own.
