The Trump admninistration 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?

The act is a sweeping wartime authority that allows noncitizens to be deported without being given the opportunity to go before an immigration or federal court judge.

WASHINGTON - The United States has removed hundreds of alleged members of the Venezuelan gang Tren de Aragua using now-blocked authority from the 1798 Alien Enemies Act, U.S. Secretary of State Marco Rubio said on Sunday.
