CHICAGO (AP) — Seeking experience in a time of war, President-elect Barack Obama will keep Defense Secretary Robert Gates in that job — if only temporarily — and he has chosen a retired Marine general to be his national security adviser, officials said Tuesday. Gates and retired Gen. James Jones bring years of experience to the Cabinet of a 47-year-old commander in chief with a relatively thin foreign policy resume. Obama, who rolled out the key components of his economic team this week, plans to announce his foreign policy braintrust after the Thanksgiving holiday. Gates, who has served as President George W. Bush’s defense chief for two years, will remain in the Cabinet for some time, probably a year, according to an official.—-Contact The Daily Reveille’s news staff at [email protected]
