US First Lady Michelle Obama has surprised children by answering their calls to a system that tracks Santa’s global gift-delivering progress.
Mrs Obama took calls to Norad’s Santa hotline for about 40 minutes.
Norad, the US and Canadian aerospace and maritime defence system, says it uses its radar and satellites to track Santa.
Mrs Obama told one child caller her husband was “kind of funny – fun to hang out with”.
The North American Aerospace Defence Command (Norad) has been tracking Santa since 1955.
