El Salvador takes in hundreds of Venezuelan gang members from US, even as judge moves to block deportations

"Today, the first 238 members of the Venezuelan criminal organization, Tren de Aragua, arrived in our country. They were immediately transferred to CECOT, the Terrorism Confinement Center, for a period of one year (renewable)," El Salvador President Nayib Bukele posted to X on Sunday morning, accompanied by video footage of planes on a tarmac. 

"On this occasion, the U.S. has also sent us 23 MS-13 members wanted by Salvadoran justice, including two ringleaders. One of them is a member of the criminal organization's highest structure," he added. 

Tren de Aragua is a Venezuelan-connected gang that has infiltrated communities in states such as Colorado and Texas, while MS-13 is a Los Angeles-founded gang with ties to El Salvador that has deep roots in California and other states such as Maryland. The State Department designated both gangs as foreign terrorist organizations last month. 

Secretary of State Marco Rubio celebrated the Salvadoran president as "the strongest security leader in our region" and "a great friend of the U.S." for accepting the criminal illegal aliens. 

Boasberg ordered on Saturday that the Trump administration is barred from using the wartime powers act to deport the illegal aliens. He added that he heard "flights are actively departing" and ordered them to return. 

"We can send them, and he will put them in his jails," Rubio told reporters back in February of Bukele's offer "And, he's also offered to do the same for dangerous criminals currently in custody and serving their sentences in the United States, even though they're U.S. citizens or legal residents."

El Salvador's CECOT prison is known as the nation's most notorious prison. The prison, which can hold 40,000 inmates, was built to house gang members in a country that held one of the highest murder rates in the world before the violence dropped in recent history. Prisoners at CECOT are blocked from receiving visitors, can only attend hearings virtually, while the prison itself blocks any cell signal to ensure gang members cannot contact criminals still on the street, various media reports have detailed. 

"The United States will pay a very low fee for them, but a high one for us. Over time, these actions, combined with the production already being generated by more than 40,000 inmates engaged in various workshops and labor under the Zero Idleness program, will help make our prison system self-sustainable. As of today, it costs $200 million per year," Bukele added on X on Sunday. 

"As always, we continue advancing in the fight against organized crime. But this time, we are also helping our allies, making our prison system self-sustainable, and obtaining vital intelligence to make our country an even safer place. All in a single action. May God bless El Salvador, and may God bless the United States."
