Donald Trump has compared people entering the United States from Mexico to invaders and said they should be immediately sent back without appearing before a judge.
The American Civil Liberties Union said in response that such a step would be illegal and violate the Constitution that Trump swore to uphold as the US President.
"We cannot allow all of these people to invade our Country," Trump said on Twitter as he was being driven to his private golf club in Northern Virginia. "When somebody comes in, we must immediately, with no Judges or Court Cases, bring them back from where they came. Our system is a mockery to good immigration policy and Law and Order."
Trump added: "Most children come without parents ... Our Immigration policy, laughed at all over the world, is very unfair to all of those people who have gone through the system legally and are waiting on line for years! Immigration must be based on merit - we need people who will help to Make America Great Again!"
Omar Jadwat, director of the ACLU's Immigrants' Rights Project, said: "What President Trump has suggested here is both illegal and unconstitutional. Any official who has sworn an oath to uphold the Constitution and laws should disavow it unequivocally."
