He gave his daughter to the Kushner family. A lot of us regular folks don't realize that the "blue bloods" still abide by a sort of feudalistic system. Arranged marriages to join houses and consolidate political power and resources. Or did Trump's daughter genuinely fall in love with Kushner, who I'm quite certain is a homosexual? Lol. This was common in feudal societies, too- some fag ruler would marry a lord's or count's daughter just to keep up the appearances and produce an heir.
