WASHINGTON (Reuters) - President Donald Trump set off a Christmas social media storm when he asked whether a 7-year-old was too old to believe in Santa Claus, capping a week of plunging stocks, a government shutdown and the U.S. defence chief's unceremonious departure.
Twitter lit up like a Christmas tree after Trump made his remark during a holiday event with first lady Melania Trump, taking calls from children calling the North American Aerospace Defense Command Santa tracker.
