The first couple helped children track Santa via the NORAD Tracks Santa program, The Associated Press reported.
The program wasn't affected by the government shutdown, because it's run by volunteers at Peterson Air Force Base in Colorado and uses preapproved funding, the AP reported.
Trump asked a 7-year-old boy if he was still a believer in Santa before adding, “Because at 7, it’s marginal, right?”
Mrs. Trump said on Twitter that helping children track Santa has become one of her favorite traditions.
