You are mistaken! The congressional law and constitution require due process before big govt, can imprison you, or send you to a foreign country to pay them to imprison you.
That is why Trump is illegally using the Alien Enemies act to deport them, so he could send the Venezuelan alleged gang members to ElSalvador for ElSalvador to imprison them for Trump, of which Trump is paying them, WITHOUT FOLLOWING IMMIGRATION LAW which requires under law, due process for those being imprisoned....During a Declared War, an exception can be made on imprisonment without a crime.
The Act was used only 3 times, all 3 times during DECLARED WARS, WWI, WWII etc....
