Secretary of State Marco Rubio testified Tuesday in a packed federal courtroom in Miami, taking the unusual step of appearing as a witness in the criminal trial of David Rivera, a former Republican congressman and onetime close ally accused of secretly lobbying Congress and the White House on behalf of Venezuelan strongman Nicolás Maduro.
Rivera, 60, was arrested in December 2022 on charges of money laundering and representing a foreign government without registering, Fox News reported. Prosecutors allege he signed a $50 million consulting contract with Venezuela's socialist government and then worked to arrange high-level meetings for regime officials, including then-Foreign Minister Delcy Rodríguez, who is now Venezuela's acting president.
Rubio's testimony offered a window into how the scheme allegedly operated: through personal trust, old political friendships, and the kind of access that only a sitting U.S. senator can provide.
Rubio told the court that he and Rivera became "very close" after overlapping for six years as members of the Florida Legislature in the early 2000s. That closeness is central to understanding the prosecution's theory of the case. Rivera didn't need a lobbyist's Rolodex. He had something better: a direct line to one of the most prominent voices on Latin American policy in the United States Senate.
According to Rubio's testimony, Rivera called him in July 2017 and said he was working with Raul Gorrin, a media magnate in Venezuela described as Rivera's main conduit to the Maduro government, on a plan to persuade Maduro to step aside. The next morning, Rivera traveled to Washington and met Rubio at his home.
Rubio said he was frank about his doubts. He called himself "skeptical" and described intermediaries in Venezuelan politics as "double dealers." But he didn't shut the door. As he explained to the court:
"But if there was a 1% chance it was real, and I had a role to play alerting the White House, I was open to doing that."
That one-percent gamble is worth pausing on. Rubio wasn't naive. He knew the terrain. But a sitting senator confronted with even a slim possibility that a brutal regime might negotiate its own exit has a reasonable basis for engaging. The question at trial isn't whether Rubio acted improperly. The indictment itself makes clear he didn't. The question is whether Rivera exploited that trust for a $50 million payday.
Rubio testified that Rivera provided him with specific language designed to signal credibility to Maduro regime insiders:
"He provided me with insight into some of the key phrases that regime insiders would've wanted to hear to know this was serious."
Rubio said he used those talking points to craft and deliver a speech on the Senate floor. The phrase Rivera suggested as the message to Venezuela's ruling class: "No vengeance, no retribution."
On its face, that language sounds diplomatic. In context, it allegedly served as a signal to a socialist dictatorship that its leaders could negotiate safe passage if they relinquished power. The prosecution's argument is that Rivera wasn't brokering peace. He was earning a fee.
Prosecutor Roger Cruz laid the foundation in his opening statement Monday, framing the case in terms that left little room for ambiguity: "This case is about two things: greed and betrayal."
Cruz told the jury that Rivera and his co-defendant made "a pact to secretly lobby for Nicolás Maduro" in exchange for $50 million. The indictment alleges Rivera was part of a conspiracy that began around the start of the Trump administration to lobby on Venezuela's behalf without registering under the Foreign Agents Registration Act.
The details prosecutors have surfaced paint a picture of operatives who understood they were operating in the shadows. Court filings reference:
When your communication strategy requires fruit-based euphemisms for cash, you're not running a legitimate consulting operation.
Rivera's attorney has pushed back on the prosecution's narrative, arguing that the three-month contract focused on luring Exxon back to Venezuela and that Rivera's separate efforts with the Venezuelan opposition were unrelated to the consulting work. The defense contends Rivera did not need to register as a foreign agent because his work was generally exempt from the Foreign Agents Registration Act.
That's a narrow legal argument, and jurors will have to weigh it against the mountain of circumstantial evidence the prosecution is stacking up. A $50 million contract. Code names. Secret lobbying efforts aimed at the highest levels of the U.S. government. The defense will need more than a technicality to explain all of that away.
This trial is a reminder that foreign influence operations don't always arrive through cyberattacks or disinformation campaigns. Sometimes they arrive through old friendships and a phone call on a summer afternoon. The Maduro regime, desperate to survive international pressure, allegedly found a former congressman willing to trade on his relationships for an extraordinary sum.
The Foreign Agents Registration Act exists precisely for moments like this. It's not a bureaucratic formality. It's a firewall between American policymakers and foreign governments that would manipulate them through back channels. When that firewall fails, the integrity of the entire legislative process is compromised.
Rubio, for his part, appears to have been the mark, not the co-conspirator. The indictment clears him of wrongdoing. But the fact that a former roommate and close political ally could allegedly weaponize that relationship on behalf of a socialist dictator should unsettle anyone who cares about the security of American institutions.
Rivera's defense will get its turn. The jury will decide whether $50 million bought a consulting contract or a conspiracy. But no matter the verdict, the trial has already exposed something worth remembering: the Maduro regime didn't just impoverish its own people. It allegedly reached into the halls of Congress and tried to buy influence with American lawmakers' own colleagues.
That's not diplomacy. That's infiltration.
