The Maryland Democrat flew to the Central American country Wednesday with the goal of meeting with Abrego Garcia, who the Trump administration says was mistakenly deported.

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.

Democratic U.S. Senator Chris Van Hollen said on Thursday he met Kilmar Abrego Garcia, a man wrongly deported to El Salvador by the administration of Republican President Donald Trump.
