WASHINGTON (AP) — The inspector general for the nation’s international aid agency is probing a once-secret Obama administration program that created a social media network in Cuba, The Associated Press has learned.

The review centers on the U.S. Agency for International Development’s Twitter-like service in Cuba, which was meant to circumvent Internet restrictions on the island and undermine the government. USAID has been criticized for using the program to conduct overt political messaging and for not fully informing Congress about the scope of its work there.
