CARACAS, Venezuela — Venezuela released 10 jailed Americans on Friday in exchange for getting home scores of migrants deported by the United States to El Salvador months ago under the Trump administration’s immigration crackdown, officials said.

The complex, three-country arrangement represents a diplomatic achievement for Venezuelan President Nicolás Maduro, helps President Donald Trump in his goal of bringing home Americans jailed abroad and lands Salvadoran President Nayib Bukele a swap that he proposed months ago.

“Every wrongfully detained American in Venezuela is now free and back in our homeland,” Secretary of State Marco Rubio said in a statement in which he thanked Bukele, a Trump ally.

Bukele said El Salvador had handed over all the Venezuelan nationals in its custody. Maduro described Friday as “a day of blessings and good news for Venezuela.” He called it “the perfect day for Venezuela.”

Central to the deal are more than 250 Venezuelan migrants freed by El Salvador, which in March agreed to a $6 million payment from the Trump administration to house them in its notorious prison.

That arrangement drew immediate blowback when Trump invoked an 18th century wartime law, the Alien Enemies Act, to quickly remove the men that his administration had accused of belonging to the violent Tren de Aragua street gang, teeing up a legal fight that reached the U.S. Supreme Court. The administration did not provide evidence to back up those claims.

The Venezuelans have been held in a mega-prison known as the Terrorism Confinement Center, or CECOT, which was built to hold alleged gang members in Bukele’s war on the country’s gangs. Human rights groups have documented hundreds of deaths as well as cases of torture inside its walls.

Lawyers have little access to those in the prison, which is heavily guarded, and information has been locked tight, other than heavily produced state propaganda videos showing tattooed men packed behind bars.

Photos and videos released by El Salvador’s government on Friday showed shackled Venezuelans sitting in a fleet of buses and boarding planes surrounded by officers in riot gear. One man looked up and pointed toward the sky as he climbed aboard a plane, while another made an obscene gesture toward police.

After arriving in Venezuela, some of the migrants crossed themselves, cried and hugged one another. They wore face masks and street clothes.

Maduro alleged that some of them were subjected to various forms of abuse at the Salvadoran prison, and one of them even lost a kidney “due to the beatings he received.”

Interior Minister Diosdado Cabello told reporters the men would undergo medical tests and background checks before they can go home.

In April, in a heated exchange of diplomatic letters with Venezuela, Bukele proposed exchanging the Venezuelans for the same number of what he called “political prisoners” held by Maduro. It provoked a harsh response from Venezuelan authorities, who called his comments “cynical” and referred to Bukele as a “neofascist.”

The State Department office responsible for negotiating the release of American detainees posted a photo Friday evening of the newly released prisoners smiling for the camera inside an airplane bringing them home, some clutching an unfurled American flag.

Among those released was 37-year-old Lucas Hunter, whose family says he was kidnapped in January by Venezuelan border guards from inside Colombia, where he was vacationing.

“We cannot wait to see him in person and help him recover from the ordeal,” his younger sister Sophie Hunter said.

Venezuelan authorities detained nearly a dozen U.S. citizens in the second half of 2024 and linked them to alleged plots to destabilize the country.

“We have prayed for this day for almost a year. My brother is an innocent man who was used as a political pawn by the Maduro regime,” said a statement from Christian Casteneda, whose brother Wilbert, a Navy SEAL, was arrested in his Caracas hotel room last year.

Global Reach, a nonprofit organization that had advocated for his release and that of several other Americans, said Venezuelan officials initially and falsely accused him of being involved in a coup but backed off that claim.

The release of the Venezuelans, meanwhile, is an invaluable win for Maduro as he presses his efforts to assert himself as president despite credible evidence that he lost reelection last year.

Long accused of human rights abuses, Maduro for months has used the migrants’ detention in El Salvador to flip the script on the U.S. government, forcing even some of his strongest political opponents to agree with his condemnation of the migrants’ treatment.
