Vornado and the Trump Organization are jointly invested in two buildings: one in Manhattan and another in San Francisco. Vornado is also in the midst of negotiations with the Kushner Co. about the future of a troubled investment by Kushner's family in a New York City skyscraper at 666 Fifth Ave., according to a Kushner Co. spokesman. The company came to the rescue of the Kushners when it agreed to an arrangement that gave Vornado 49.5 percent of the office portion of the New York tower and 70 percent of the retail space.
