Liberal billionaire George Soros’ foundation is among the most opaque think tanks in the country, according to a study funded by that foundation. The study, by a group called Transparify, ranked 35 U.S. think tanks based on the amount of financial information that they make publicly available. Soros’ Open Society Foundations rank dead last, earning zero stars out of a possible five. That designation is reserved for groups that dislose “no relevant or up-to-date information” on their finances.
