A federal judge on Friday ordered the Justice Department to tell her more about a deal struck between the Trump administration and President Nayib Bukele of El Salvador to imprison immigrants deported from the United States in a Salvadoran maximum-security facility in exchange for the return of top leaders of the MS-13 gang who are in U.S. custody.
The order by the judge, Joan M. Azrack, came as she was considering a request by federal prosecutors on Long Island to dismiss sprawling narco-terrorism charges against Vladimir Arévalo Chávez, who is alleged to be one of those leaders, in preparation for sending him back to El Salvador.
In exchange for taking the deportees, the Bukele government received millions of dollars from the United States, as well as the Trump administration’s pledge to return top MS-13 leaders who are facing charges in federal court.
An investigation by The New York Times found that the returning of the gang leaders to El Salvador was threatening a long-running federal investigation into the upper echelons of MS-13. Prosecutors had amassed substantial evidence of ties between the gang and the Bukele administration — and had been scrutinizing Mr. Bukele himself, The Times found.
