The Trump Administration appeared to openly defy multiple court orders over the weekend involving deportations of hundreds of people.

The Constitution offers the president the unique and irrefutable power to issue pardons. In one of his final acts in office, Biden issued a slew of controversial preemptive pardons in January for individuals who had not committed crimes but had investigated, criticized, or worked to prosecute Trump for criminal wrongdoing.

The U.S. government paid El Salvador about $6 million to receive the deportees, the White House said. A hearing on the legality of the deportations was adjourned until Tuesday.
