The “administrative error” that caused a Maryland man’s deportation to a notorious prison in El Salvador has prompted backlash in Congress and beyond.

The government has deported hundreds of migrants over alleged gang ties, but their families claim their loved ones are innocent and lack due process.

The Trump administration said the court didn’t have the authority to order the return of Kilmar Abrego Garcia.

Despite the mistake, officials said Kilmar Armando Abrego Garcia can't be brought back since he is no longer in U.S. custody.

The Trump administration said Monday it deported another 17 alleged gang members to El Salvador for incarceration in the notorious Terrorism Confinement Center prison. The 10 Salvadoran and seven Venezuelan men were flown to El Salvador on Sunday evening from Guantánamo Bay aboard a military C-17 aircraft.

The State Department deported more immigrants to El Salvador over the weekend. Secretary of State Marco Rubio called the removals a “successful counter-terrorism operation.” It comes after a federal judge had blocked the administration from invoking a rare wartime authority to deport hundreds of migrants without due process.
