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.

The Trump administration has invoked a 227-year-old law, the Alien Enemies Act, to target Tren de Aragua, a gang with its roots in the prisons of Venezuela. Who are they and how wide is their reach?

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.
