A who’s who of government, business and international finance lost a total of more than $600 million they had invested in scandal-plagued Theranos Inc., according to previously sealed documents made public in a lawsuit, the Wall Street Journal reported. High on the list is Education Secretary Betsy DeVos, whose family invested $100 million in the Silicon Valley blood-testing company, the documents show. DeVos had previously disclosed that her family was a Theranos investor in a government filing, but the size of the investment wasn’t known. President Donald Trump’s education secretary is among a number of prominent figures who poured money into Theranos between 2013 and 2015 before a series of Wall Street Journal articles revealed that the company was encountering problems with its technology and misleading its investors.
