The dispute over the wrongful deportation and imprisonment of Kilmar Abrego Garcia “is not only about one man” but about Donald Trump's disregard of the American judicial system as well, Sen. Chris Van Hollen said Friday as he returned from a three-day trip to El Salvador to press for the detained man's release.

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.
