Kilmar Abrego Garcia, 29, has been in El Salvador’s Terrorism Confinement Center for almost a month. Here’s everything that’s happened since he was arrested on March 12.

DULLES, Va. - Maryland Democratic Sen. Chris Van Hollen flew into Dulles Airport on Friday after visiting a wrongly deported man in El Salvador. The senator says he learned that the Trump administration struck a $15 million deal with the Central American nation to take deportees from the United States.

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.
