One of two Americans detained Monday in Venezuela has reportedly said he was on a mission to kidnap President Nicolas Maduro in an effort for President Donald Trump to topple Maduro’s government.

Luke Denman, 34, and Airan Berry, 41, were detained on suspicion, according to CBS News, of plotting to topple Maduro.

Trump has said the United States had nothing to do with the purported attack.

Jordan Goudreau, a 43-year-old former Green Beret who is head of Silvercorp USA, reportedly is the leader behind the plot. He is under federal investigation for arms trafficking, according to current and former U.S. law enforcement officials. Nonetheless, the Venezuelan leader insists his U.S. adversary was behind the apparent attempt to force him out.

“There’s the proof,” he said, pointing to the video, in which Denman indicates that Trump was behind Silvercorp’s incursion. “And there will be more.”

Nonetheless, opposition critics and observers said the testimony should be taken with a grain of salt, noting that Venezuelan authorities have a record of forcing statements. Though Denman did not appear under duress, one expert noted that he made an unusual and exaggerated gesture with his eyes in what may have been a covert signal to those watching.

“Special operation soldiers are trained to find creative ways to discredit any propaganda videos they are forced to make if captured by the enemy,” said Ephraim Mattos, a Navy SEAL who had visited the rebel training camps in Colombia but was not involved in the operation.

He said the odd eye movement immediately after saying Trump was Goudreau’s boss is “a clear sign from Luke that he is being forced.”

The confusing events have sparked new tensions between Venezuela and the U.S., which has been a staunch ally of opposition leader Juan Guaidó, the lawmaker recognized by nearly 60 nations as the country’s legitimate president. U.S. Secretary of State Mike Pompeo reiterated Trump’s claims Wednesday from a day earlier that there was no direct U.S. involvement.

“If we’d have been involved, it would have gone differently,” he chided.

Democratic congressional staff, meanwhile, contacted the State Department multiple times Monday seeking any information about possible contacts with Goudreau or knowledge of his activities.

In the video aired Wednesday, Denman said Goudreau tasked him with training troops and then staging an attack to “secure” Caracas and the airport. He said he arrived in Colombia in mid-January, driving to the border with two others to instruct about 60 people.

When hints of the conspiracy surfaced last month, the Maduro-controlled state media portrayed it as an invasion ginned up by the CIA, like the Cuban Bay of Pigs fiasco of 1961. An Associated Press investigation found no evidence of U.S. government involvement in the plot.

Maduro appeared on state television Monday to show Denman’s and Berry’s passports.

The alleged plot’s goal was to install Guaidó as Venezuela’s rightful leader.

According to details from The Associated Press, planning for the incursion began after an April 30, 2019, barracks revolt by a cadre of soldiers who swore loyalty to Guaidó. Contrary to U.S. expectations at the time, key Maduro aides never joined with the opposition and the government quickly quashed the uprising.

A few weeks later, some soldiers and politicians involved in the failed rebellion retreated to the JW Marriott in Bogota, Colombia. The hotel was a center of intrigue among Venezuelan exiles. For this occasion, conference rooms were reserved for what one participant described as the “Star Wars summit of anti-Maduro goofballs” — military deserters accused of drug trafficking, shady financiers and former Maduro officials seeking redemption.

Among those angling in the open lobby was Goudreau, a three-time Bronze Star recipient for bravery in Iraq and Afghanistan, where he served as a medic in U.S. Army special forces, according to five people who met with the former soldier.

The plan was simple but perilous. Some 300 heavily armed volunteers would sneak into Venezuela from the northern tip of South America. Along the way, they would raid military bases in the socialist country and ignite a popular rebellion that would end in Maduro’s arrest.

Those Goudreau interacted with in the U.S. and Colombia described him in interviews alternately as a freedom-loving patriot, a mercenary and a gifted warrior scarred by battle and in way over his head.

At the end of an otherwise-distinguished military career, the Canadian-born Goudreau was investigated in 2013 for allegedly defrauding the Army of $62,000 in housing stipends. Goudreau said the investigation was closed with no charges.

After retiring in 2016, he worked as a private security contractor in Puerto Rico following Hurricane Maria. In 2018, he set up Silvercorp USA, a private security firm, near his home on Florida’s Space Coast to embed counter-terror agents in schools disguised as teachers.

Silvercorp’s website touts operations in more than 50 countries, with an advisory team made up of former diplomats, experienced military strategists and heads of multinational corporations -- none of them named. It claims to have “led international security teams” for the president of the United States.

When hints of the conspiracy surfaced last month, the Maduro-controlled state media portrayed it as an invasion ginned up by the CIA, like the Cuban Bay of Pigs fiasco of 1961. An Associated Press investigation found no evidence of U.S. government involvement in the plot.

Nevertheless, interviews revealed that leaders of Venezuela’s U.S.-backed opposition knew of the covert force, even if they dismissed its prospects.

Goudreau had been introduced to Keith Schiller, Trump’s longtime bodyguard, through someone who worked in private security. Schiller attended a March 2019 event at the University Club in Washington for potential donors with activist Lester Toledo, then Guaidó’s coordinator for the delivery of humanitarian aid.

Last May, Goudreau accompanied Schiller to a meeting in Miami with representatives of Guaidó. There was a lively discussion with Schiller about the need to beef up security for Guaidó and his growing team of advisers inside Venezuela and across the world, according to a person familiar with the meeting. Schiller thought Goudreau was naive and in over his head. He cut off all contact following the meeting, said a person close to the former White House official.

In Bogota, it was Toledo who introduced Goudreau to a rebellious former Venezuelan military officer the American would come to trust above all others — Cliver Alcalá, ringleader of the Venezuelan military deserters.

Alcalá, a retired major general in Venezuela’s army, seemed an unlikely hero to restore democracy to his homeland. In 2011, he was sanctioned by the U.S. for allegedly supplying FARC guerrillas in Colombia with surface-to-air missiles in exchange for cocaine. And last month, Alcalá was indicted by U.S. prosecutors alongside Maduro as one of the architects of a narcoterrorist conspiracy that allegedly sent 250 metric tons of cocaine every year to the U.S.

Alcalá is now in federal custody in New York awaiting trial. But before his surrender in Colombia, where he had been living since 2018, he had emerged as a forceful opponent of Maduro, not shy about urging military force.

During two days of meetings with Goudreau and Toledo at the JW Marriott, Alcalá explained how he had selected 300 combatants from among the throngs of low-ranking soldiers who abandoned Maduro and fled to Colombia in the early days of Guaidó’s uprising, said three people who participated in the meeting and insisted on anonymity to discuss sensitive conversations.

Alcalá said several dozen men were already living in three camps he maintained in and around the desert-like La Guajira peninsula that Colombia shares with Venezuela, the three said. Among the combatants in the camps was an exiled national guardsman accused of participating in a 2018 drone attack on Maduro.

Goudreau told Alcalá his company could prepare the men for battle, according to the three sources. The two sides discussed weapons and equipment for the volunteer army, with Goudreau estimating a budget of about $1.5 million for a rapid-strike operation.

Goudreau told participants at the meeting that he had high-level contacts in the Trump administration who could assist the effort, although he offered few details, the three people said. Over time, many of the people involved in the plan to overthrow Maduro would come to doubt his word.

From the outset, the audacious plan split an opposition coalition already sharply divided by egos and strategy. There were concerns that Alcalá, with a murky past and ties to the regime through a brother who was Maduro’s ambassador to Iran, couldn’t be trusted. Others worried about going behind the backs of their Colombian allies and the U.S. government.

But Goudreau didn’t share the concerns about Alcalá, according to two people close to the former American soldier. Over time, he would come to share Alcalá’s mistrust of the opposition, whose talk of restoring democracy was belied by what he saw as festering corruption and closed-door deal making with the regime, they said.

More important to Goudreau, Alcalá retained influence in the armed forces that Maduro’s opponents, mostly civilian elites, lacked. He also knew the terrain, having served as the top commander along the border.

Guaidó’s envoys, including Toledo, ended contact with Goudreau after the Bogota meeting because they believed it was a suicide mission, according to three people close to the opposition leader.

Undeterred, Goudreau returned to Colombia with four associates, all of them U.S. combat veterans, and began working directly with Alcalá.

Alcalá and Goudreau revealed little about their military plans when they toured the camps. Some of the would-be combatants were told by the two men that the rag-tag army would cross the border in a heavily armed convoy and sweep into Caracas within 96 hours, according to multiple soldiers at the camps. Goudreau told the volunteers that — once challenged in battle — Maduro’s food-deprived, demoralized military would collapse like dominoes, several of the soldiers said.

Many saw the plan as foolhardy and there appears to have been no serious attempt to seek U.S. military support.

The AP found no indication U.S. officials sponsored Goudreau’s actions nor that Trump has authorized covert operations against Maduro, something that requires congressional notification.

But Colombian authorities were aware of his movements, as were prominent opposition politicians in Venezuela and exiles in Bogota, some of whom shared their findings with U.S. officials, according to two people familiar with the discussions.

True to his reputation as a self-absorbed loose cannon, Alcalá openly touted his plans for an incursion in a June meeting with Colombia’s National Intelligence Directorate and appealed for their support, said a former Colombian official familiar with the conversation. Alcalá also boasted about his relationship with Goudreau, describing him as a former CIA agent.

When the Colombians checked with their CIA counterparts in Bogota, they were told that the former Green Beret was never an agent. Alcalá was then told by his hosts to stop talking about an invasion or face expulsion, the former Colombian official said.

It’s unclear where Alcalá and Goudreau got their backing, and whatever money was collected for the initiative appears to have been meager. One person who allegedly promised support was Roen Kraft, an eccentric descendant of the cheese-making family who — along with former Trump bodyguard Schiller — was among those meeting with opposition envoys in Miami and Washington.

At some point, Kraft started raising money among his own circle of fellow trust-fund friends for what he described as a “private coup” to be carried out by Silvercorp, according to two businessmen whom he asked for money.

Kraft allegedly lured prospective donors with the promise of preferential access to negotiate deals in the energy and mining sectors with an eventual Guaidó government, said one of the businessmen. He provided AP a two-page, unsigned draft memorandum for a six-figure commitment he said was sent by Kraft in October in which he represents himself as the “prime contractor” of Venezuela.

Back in Colombia, more recruits were arriving to the three camps — even if the promised money didn’t. Goudreau tried to bring a semblance of order. Uniforms were provided, daily exercise routines intensified and Silvercorp instructed the would-be warriors in close-quarter combat.

The plot quickly crumbled in early March, when one of the volunteer combatants was arrested after sneaking across the border into Venezuela from Colombia.

Shortly after, Colombian police stopped a truck transporting a cache of new weapons and tactical equipment worth about $150,000, including spotting scopes, night vision goggles, two-way radios and 26 American-made assault rifles with the serial numbers rubbed off. Fifteen brown-colored helmets were manufactured by High-End Defense Solutions, a Miami-based military equipment vendor owned by a Venezuelan immigrant family.

High-End Defense Solutions is the same company that Goudreau visited in November and December, allegedly to source weapons, according to two former Venezuelan soldiers who claim to have helped the American select the gear but later had a bitter falling out with Goudreau amid accusations that they were moles for Maduro.

Alcalá claimed ownership of the weapons shortly before surrendering to face the U.S. drug charges, saying they belonged to the “Venezuelan people.” He also lashed out against Guaidó, accusing him of betraying a contract signed between his “American advisers” and J.J. Rendon, a political strategist in Miami appointed by Guaidó to help force Maduro from power.

“We had everything ready,” lamented Alcalá in a video published on social media. “But circumstances that have plagued us throughout this fight against the regime generated leaks from the very heart of the opposition, the part that wants to coexist with Maduro.”

Through a spokesman, Guaidó stood by comments made to Colombian media that he never signed any contract of the kind described by Alcalá, whom he said he doesn’t know. Rendon said his work for Guaidó is confidential and he would be required to deny any contract, whether or not it exists.

Meanwhile, Alcalá has offered no evidence and the alleged contract has yet to emerge, though AP repeatedly asked Goudreau for a copy.

In the aftermath of Alcalá’s arrest, the would-be insurrection appears to have disbanded. As the coronavirus spreads, several of the remaining combatants have fled the camps and fanned out across Colombia, reconnecting with loved ones and figuring out their next steps. Most are broke, facing investigation by Colombian police and frustrated with Goudreau, whom they blame for leading them astray.
