MENLO PARK, CA—Not to be outdone by Google's large donationearlier this year, Facebook is also donating $1 billion during thecoming decade in affordable housing, mostly in the Golden State.The social network platform has partnered with governor GavinNewsom and others on projects intended to result in as many as20,000 new housing units for teachers, nurses, first responders andother essential workers, according to Facebook's chief financialofficer David Wehner.
