WASHINGTON (AP) — Draft messages produced for a Twitter-like network that the U.S. government secretly built in Cuba were overtly political and poked fun at the Castro brothers, documents obtained by The Associated Press show. The messages conflict with claims by the Obama administration that the program had no U.S.-generated political content and was never intended to stir unrest on the island.

Disclosure of the messages, as described in internal documents, came as the head of the U.S. Agency for International Development told Congress in sometimes- confrontational testimony Tuesday that his agency’s program was “absolutely not” covert and was simply meant to increase the flow of information.
