Their parents, Charles and Seryl Kushner (née Stadtmauer), are worth $3.2 (£2.4) billion through their ownership of a 20 per cent stake in the real estate company, Kushner Companies, which Charles founded in 1985. The remaining 80 per cent of the shares of Kushner Companies are divided equally between their children, Jared, Joshua, Nicole, and Dara. Joshua Kushner is married to media executive, entrepreneur, and former supermodel Karlie Kloss, who converted to Judaism before their wedding. Both Kloss and Joshua are registered Democrats, in spite of their familial connections to the Trump administration.
