One of Silicon Valley’s most prominent private equity investors — and one of the tech sector’s leading proponents of how to invest ethically and for social impact — has been charged in an explosive college admissions scandal that was revealed Tuesday, March 12.

Prosecutors charged Bill McGlashan, a founder and managing partner at TPG Growth — which has made landmark investments in companies like Uber and Airbnb — on fraud allegations for trying to engineer the admission of his son to the University of Southern California.

What is particularly damaging for TPG is that McGlashan has positioned himself as a leading voice in Silicon Valley for social responsibility. In addition to overseeing TPG’s late-stage growth investing arm, McGlashan has partnered with other conscious leaders like Bono and Laurene Powell Jobs at The Rise Fund, a TPG investing arm that tries to make the world a better place through investments in things like dairy farms in India.
