Music mogul David Foster's Democrat daughter Sara Foster excoriated liberal politicians who are 'ruining cities' and referred to to San Francisco as a 'complete s**thole' over the murder of CashApp founder Bob Lee. Father-of-two Lee, 43, was knifed multiple times in the chest early Tuesday as he strolled through the progressive city's well-heeled Rincon Hill neighborhood while on a business trip. Foster, 42, the daughter of music mogul David Foster and a model/actress who starred on the reboot of 90210, ripped into the left for what she feels is their responsibility for his death.
