Appearing emotional and tired, Maryland Sen. Chris Van Hollen arrived back in the United States Friday afternoon, marking his return from a trip to El Salvador where he met with mistakenly deported Kilmar Abrego Garcia.

Van Hollen, 66, got his start in politics as a staffer for former Maryland U.S. Sen. Charles Mathias in the 1980s, going on to staff the Senate Foreign Relations Committee and, later, Maryland Gov. William Donald Schaefer.
