The Alien Enemies Act of 1798 gives the president wartime powers to deport undocumented immigrants with little to no due process.

Roosevelt signed Proclamation 2525 under the Alien Enemies Act, granting the government the authority to arrest, control and remove suspected Japanese Americans deemed dangerous to the safety of the United States Dec. 7, 1941. German and Italian Americans were targeted as well.

President Trump is considering invoking the Alien Enemies Act, a law that is 200+ years old, to further his mass deportation agenda.
