Kilmar Abrego Garcia, a Maryland sheet metal worker, was wrongfully deported to a notorious prison in El Salvador.

A spokeswoman for the presidency of El Salvador, Wendy Ramos, did not respond to requests for information about Senator Van Hollen’s meeting with Abrego Garcia, including whether he had been returned to the prison where American officials have said he is being held, the Terrorism Confinement Center, or CECOT.
