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.

The senator hoped to visit Kilmar Armando Abrego Garcia at the maximum security prison where he is being held. He also hoped to talk to Salvadoran officials about securing Abrego Garcia’s release.

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.
