Immigration officials said Tomás Hernández worked in high-level posts for Cuba’s foreign intelligence agency for decades before migrating to the United States to pursue the American dream.

The 71-year-old was detained by federal agents outside his Miami-area home in March and accused of hiding his ties to Cuba’s Communist Party when he obtained permanent residency.

Cuban-Americans in South Florida have long clamored for a firmer hand with Havana and the recent apprehensions of Hernández and several other former Cuban officials for deportation have been extremely popular among the politically powerful exile community.

“It’s a political gift to Cuban-American hardliners,” said Eduardo Gamarra, a Latin American expert at Florida International University. But many Cubans fear they could be next on Trump’s list, he said, and “some in the community see it as a betrayal.”

While President Donald Trump’s mass deportation pledge has frightened migrants from many nations, it has come as something of a shock to the 2.4 million Cuban-Americans, who strongly backed the Republican twice and have long enjoyed a place of privilege in the U.S. immigration system.

Amid record arrivals of migrants from the Caribbean island, Trump in March revoked temporary humanitarian parole for about 300,000 Cubans. Many have been detained ahead of possible deportation.

Among those facing deportation is a pro-Trump Cuban rapper behind a hit song “Patria y Vida” — “Homeland and Life” — that became the unofficial anthem of anti-communist protests on the island in 2021 and drew praise from the likes of then Republican Sen. Marco Rubio, now Secretary of State. Eliéxer Márquez, who raps under the name El Funky, said he received notice this month that he had 30 days to leave the U.S.

Thanks to Cold War laws aimed at removing Fidel Castro, Cuban migrants for many decades enjoyed almost automatic refugee status in the U.S. and could obtain green cards a year after entry, unlike migrants from virtually every other country.

Support for Trump among likely Cuban-American voters in Miami was at an all-time high on the eve of last year’s election, according to a poll by Florida International University, which has been tracking the Cuban-American community since 1991. Trump rarely mentions Cubans in his attacks on migrant targets including Venezuelans and Haitians. That has given many Cubans hope that they will remain immune to immigration enforcement actions.

Democrats, meanwhile, have been trying to turn the immigration crackdown to their advantage. In April, grassroots groups erected two giant billboards on Miami highways calling Rubio and Republican Reps. Mario Díaz-Balart, María Elvira Salazar and Carlos Giménez “traitors” to the Cuban-American community for failing to protect tens of thousands of migrants from Trump’s immigration policies.

In March, Giménez sent Homeland Security Secretary Kristi Noem a letter with the names of 108 people he said were former Cuban state agents or Communist Party officials living unlawfully in the U.S.

“It is imperative that the Department of Homeland Security enforce existing U.S. laws to identify, deport and repatriate these individuals who pose a direct threat to our national security, the integrity of our immigration system and the safety of Cuban exiles and American citizens alike,” Giménez wrote, adding that the U.S. remains a “beacon of hope and freedom for those escaping tyranny.”

Giménez’s target list was compiled by Luis Dominguez, who left Cuba in 1971 and has made it his mission to topple Cuba’s government. In 2009, when the internet was still a novelty in Cuba, Dominguez said he posed as a 27-year-old female sports journalist from Colombia to lure Castro’s son Antonio into an online romance.

With support from the right-wing Foundation for Human Rights in Cuba, he started combing social media and relying on a well-oiled network of anti-socialist sources, inside Cuba and outside the country, to dox officials allegedly behind human rights abuses and violations of democratic norms. To date, his website, Represores Cubanos — Cuban Repressors — has identified more than 1,200 such state agents, some 150 in the United States.

“They’re chasing the American dream, but previously they condemned it while pursuing the Cuban dream,” Dominguez said. “It’s the typical double life of any Communist regime. When they were in power they criticized anything about the U.S. But now that they’re here, they love it.”

Dominguez, 62, said he regularly shares his findings with federal law enforcement but a spokesman for U.S. Immigration and Customs Enforcement didn’t comment on the agency’s relationship with the activist.

Enrique Garcia, a former colleague, said he studied with Hernández in the former Soviet Union in the 1970s. Upon their return, Hernández was sent to work in the spy agency’s elite “North America” department, said Garcia.

Garcia, who defected to the U.S. in the 1990s and has devoted himself to helping American spy catchers unmask Cuban agents, said one-time Cuban agents have infiltrated the current migration wave while hiding their past and even current loyalties to the Cuban government.
