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.

Sen. Chris Van Hollen (D-Md.) met with Kilmar Abrego Garcia on Thursday in San Salvador. President Trump calls the Maryland resident a 'very violent person.'

The little-noticed episode was a key part of the long saga of Abrego Garcia, the Salvadorian sheet metal apprentice living in Maryland who was accused of being an MS-13 gang member and mistakenly sent in March by the Trump administration to El Salvador’s notorious CECOT prison.

The Supreme Court blocked the Trump administration from deporting a second wave of Venezuelan immigrants under the Alien Enemies Act after lawyers rushed to the court and alleged that the administration was about to send dozens or hundreds of detainees to El Salvador in defiance of an earlier ruling by the justices.

A federal appeals court said it will not pause a district court order that required the Trump administration to facilitate the release of Kilmar Abrego Garcia from El Salvador.
