The government has not publicly said what information Rocha might have divulged to Cuba or how he could have influenced U.S. policy. Rocha held high-level security clearances, giving him access to top secret information, according to the indictment.

Rocha had at least three meetings with an undercover FBI agent, whom the retired diplomat believed to be a representative of Cuba’s spy agency. He referred to the U.S. as “the enemy” and said “what we have done” was “enormous” and “more than a grand slam,” according to the criminal complaint.
