Trump on Sunday called for undocumented immigrants who illegally enter the U.S. to be sent “back from where they came” without going through the judicial process in deportation cases.

We cannot allow all of these people to invade our Country. 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. Most children come without parents... said Trump in his latest tweets on June 24,2028. 

Trump's call to eliminate due process from deportation cases is likely to draw fire from critics and immigration advocates.

Trump has made a crackdown on immigration a key element of his administration. He has long railed for stronger immigration laws since the start of his campaign, including his promise to build a wall on the U.S.-Mexico border and have Mexico pay for it.

His administration implemented a "zero-tolerance" policy at the border earlier this year, mandating that all people apprehended illegally crossing the border face prosecution.

Trump faced backlash for the policy, which resulted in the separations of immigrant children and parents at the border, before he ended the separations last week.

Hundreds of demonstrators rallied in San Diego, McAllen, Texas, on Saturday to protest the Trump administration's recently halted practice of separating immigrant families at the US-Mexico border.

They were gathered to march in El Paso, Texas toward the town of Tornillo, where there's a tent encampment to house migrant children separated from their parents under the US president Donald Trump administration's zero-tolerance policy toward people trying to cross the border into the U.S.

Nearly 2,000 children have been separated from their families between April and May, according to the Department of Homeland Security.

The executive order signed by the US President on 20 June 2018 fails to address the situation of thousands of migrant children forcibly separated from their parents and held in detention at the border, UN experts said. In addition, it may lead to indefinite detention of entire families in violation of international human rights standards, they said.
