Maryland Senator Chris Van Hollen shared an update on his trip to El Salvador, saying he was denied a meeting with Kilmar Abrego Garcia, the man who was mistakenly deported and remains in prison.

US Sen. Chris Van Hollen traveled to El Salvador Wednesday seeking to meet with government officials there about Kilmar Abrego Garcia, a man who had been living in his state until he was mistakenly deported by the Trump administration last month to a mega-prison in the Central American nation.

El Salvador’s government rebuffed a request Wednesday from Sen. Chris Van Hollen (D-Maryland) to free Kilmar Abrego García, whose case has become a flash point in the battle over President Donald Trump’s mass deportation campaign since the administration mistakenly deported him last month.
