“The government’s head of background investigations is fully in favor of moving his office, staff and workload under the Defense Department, a shift that is expected to become official under an impending presidential executive order. Congress passed legislation last year requiring the National Background Investigations Bureau—part of the Office of Personnel Management—to transfer investigations of Defense personnel and contractors to that department. NBIB would retain only the civilian government portion, but that partial shift would ultimately be untenable, according to administration officials.”
