In July 2010, Joe McSpedon, a U.S. government official, flew to Barcelona to put the final touches on a secret plan to build a social media project aimed at undermining Cuba’s communist government.

McSpedon and his team of high-tech contractors had come in from Costa Rica and Nicaragua, Washington and Denver. Their mission: to launch a messaging network that could reach hundreds of thousands of Cubans. To hide the network from the Cuban government, they would set up a byzantine system of front companies using a Cayman Islands bank account, and recruit unsuspecting executives who would not be told of the company’s ties to the U.S. government.

McSpedon didn’t work for the CIA. This was a program paid for and run by the U.S. Agency for International Development, best known for overseeing billions of dollars in U.S. humanitarian aid.

According to documents obtained by The Associated Press and multiple interviews with people involved in the project, the plan was to develop a bare-bones “Cuban Twitter,” using cellphone text messaging to evade Cuba’s strict control of information and its stranglehold restrictions over the Internet. In a play on Twitter, it was called ZunZuneo — slang for a Cuban hummingbird’s tweet.

Documents show the U.S. government planned to build a subscriber base through “non-controversial content”: news messages on soccer, music, and hurricane updates. Later when the network reached a critical mass of subscribers, perhaps hundreds of thousands, operators would introduce political content aimed at inspiring Cubans to organize “smart mobs” — mass gatherings called at a moment’s notice that might trigger a Cuban Spring, or, as one USAID document put it, “renegotiate the balance of power between the state and society.”

At its peak, the project drew in more than 40,000 Cubans to share news and exchange opinions. But its subscribers were never aware it was created by the U.S. government, or that American contractors were gathering their private data in the hope that it might be used for political purposes.

“There will be absolutely no mention of United States government involvement,” according to a 2010 memo from Mobile Accord, one of the project’s contractors. “This is absolutely crucial for the long-term success of the service and to ensure the success of the Mission.”

The program’s legality is unclear: U.S. law requires that any covert action by a federal agency must have a presidential authorization. Officials at USAID would not say who had approved the program or whether the White House was aware of it. McSpedon, the most senior official named in the documents obtained by the AP, is a mid-level manager who declined to comment.

USAID spokesman Matt Herrick said the agency is proud of its Cuba programs and noted that congressional investigators reviewed them last year and found them to be consistent with U.S. law.

“USAID is a development agency, not an intelligence agency, and we work all over the world to help people exercise their fundamental rights and freedoms, and give them access to tools to improve their lives and connect with the outside world,” he said.

“In the implementation,” he added, “has the government taken steps to be discreet in non-permissive environments? Of course. That’s how you protect the practitioners and the public. In hostile environments, we often take steps to protect the partners we’re working with on the ground. This is not unique to Cuba.”
