Nominated: White House Chief of Staff Jack Lew.
SECRETARY OF DEFENSE
Leon Panetta is likely to leave in mid-February, if his replacement is confirmed.
Nominated: Chuck Hagel, a former Republican senator, is facing opposition from fellow Republicans because of his positions on Iran -- he opposed unilateral sanctions -- and Israel. His confirmation hearings begin Jan. 31.
Eric Holder will remain, although it remains unclear how long he will stay.
Former Sen. Ken Salazar announced this month that he would leave by the end of March to return home to Colorado.

CHIEF OF STAFF
Jack Lew has been nominated to be Treasury secretary.
Expected nomination: Denis McDonough, Deputy National Security Adviser and a native of Stillwater, Minn., is expected to be named this week. The job does not require confirmation.
Thomas Vilsack confirmed last week that he is staying.
