Melania Trump often seems like a reluctant first lady. But she’s stepping into the spotlight this week to take on a very traditional part of the role. Mrs. Trump is unveiling her policy priorities — as have first ladies who have come before her — which are expected to focus on children. The announcement comes at a moment when her husband is under intense scrutiny. Her spokeswoman Stephanie Grisham tells NPR there are “many issues” facing children today, and that the first lady’s initiatives will try to help them to handle those challenges. Grisham says the first lady will continue to focus on many of the subjects she has addressed in the past.
