The probe began earlier this week after a woman identified by WVLT, Channel 8, as the wife of a 278th soldier said her daughter had taken the strange calls from a man with an accent.
Diana Heerdt said the man, who claimed he was calling from Loudon, questioned her daughter about the unit's deployment timeline and when it would return home, the station reported.
Clark confirmed the caller asked about the unit's "itinerary."
A caller ID machine identified the number as originating from New Jersey.
