A firm contracted by the U.S. government to help set up a Twitter-like network in Cuba held secret level security clearance and was warned the operation could involve classified work, according to documents seen by Al Jazeera. And documents show that the program was managed by a section of the U.S. Agency for International Development (USAID) tasked with helping manage regime change in countries where U.S. interests are at stake.

Details contained in the terms of a $1.5 billion contract between USAID and Washington-based contractor Creative Associates International (CAI) and others outline the security clearance arrangements required by the U.S. government. Signed in 2008, the document had been obtained by researcher Jeremy Bigwood through a FOIA request, and shared with Al Jazeera. USAID said the document was for subsequent work put out to CAI and not the one relating to the funding of Twitter-like ZunZuneo. But Al Jazeera understands that the stated security level needed and the reference to the possibility of "classified" work is exactly the same as in the contract relating to controversial Cuba project.

Bigwood first reported on the contract in a report published Monday by the North American Congress on Latin America (NACLA). The contract details could be seen to undermine official statements that the ZunZuneo program was “discreet” but “absolutely not” covert, according to testimony USAID administrator Rajiv Shah gave before Congress.

Matt Herrick, spokesman for USAID, told Al Jazeera on Monday that references in the contract to "secret" security level being required was standard.

"Requiring partner clearance is a safeguard required in many government contracts as part of a wide-ranging federal government program that ensures government contractors and their staff have the proper controls in place to safeguard government infrastructure and information."

Herrick added that in the case of ZunZuneo, no covert work was carried out.

The ZunZuneo program was managed by the agency's Office of Transition Initiatives (OTI). Founded in 1994, OTI focuses its work on times of “high politicization and instability,” according to the 2008 contract. Among its criteria for engagement are whether a country is important to U.S. national interests and whether there is a window of opportunity for a change in government.

“Even the best-intentioned assistance can be ineffective if the situation is not ripe for change. OTI cannot create a transition or impose democracy, but it can identify and support key individuals and groups who are committed to peaceful, participatory reform,” the contract reads.

“Task orders under this contract may involve classified performance,” it states. “At the time of award, the contractor does have a secret level facilities clearance.” The contract’s final page is a Department of Defense contract security classification specification.

“This is simply not a covert effort in any regard,” Shah testified during a Senate Appropriations Subcommittee hearing on April 10.

He said of the program that “parts of it were done discreetly.” His statements supported those of White House press secretary Jay Carney, who told reporters, “USAID is a development agency, not an intelligence agency. Suggestions that this was a covert program are wrong.”
