At issue is a once-secret U.S. program that created a social media network in Cuba. The primitive service is known as ZunZuneo and was meant to circumvent Internet restrictions in Cuba.
The U.S. Agency for International Development is the nation's international-aid agency. Officials confirmed Thursday the inspector general is investigating the program.
An AP investigation found agency contractors deployed the service by hiding sources of taxpayer money, not telling subscribers it was backed by the U.S. and not revealing it gathered private user data for political purposes.
The agency has said the program conformed with U.S. law and congressional oversight. The Senate Foreign Relations Committee has asked USAID to turn over all records about similar efforts worldwide.
