BETHESDA, Md. (AP) — Melania Trump on Wednesday celebrated an early Valentine’s Day with children and young adults being treated for rare and serious diseases, joining them in holiday-themed craft-making and chatting about their lives, health and other interests. After they finished making flower bouquets and lanterns out of construction paper and other materials, they stepped over to a festively decorated dessert bar laid out with mini cupcakes and jars of mini chocolates and other candies.
