Tren de Aragua, a gang born out of a Venezuelan prison, is a loose network that doesn’t operate like groups typically considered terrorist organizations.

Trump applauded Bukele for his "understanding of this horrible situation" as 250 Tren de Aragua members and 23 MS-13 members were deported to El Salvador.

The deportation of 261 Venezuelans, including suspected members of the gang, was carried out on Saturday. By the time a federal court halted the move, two planes carrying immigrants had already left the country.

A federal judge has stopped US President Donald Trump from using a 227-year-old law meant to protect the US during wartime to carry out mass deportations of Venezuelans. Trump proclaimed on Saturday that immigrants belonging to the Venezuelan crime gang Tren de Aragua were "conducting irregular warfare" against the US and that he would deport them under the Alien Enemies Act of 1798.

Trump invoked the Alien Enemies Act against Tren de Aragua members. A federal judge later ordered the administration to turn around any planes that had already taken off.
