At the time, Ivanka also admitted that she has a great partner in her husband. “[Jared] is really incredibly hands on as a dad. For him what’s most important is his family,” she said. “So we work really hard during the week and we really prioritize weekends for just being sort of reconnecting as a family. It’s very seldom that we’ll have a commitment on a Saturday or a Sunday. It’s really about us being together.”
