President Donald Trump signed an executive order Wednesday to bar undocumented migrants from accessing public benefits, even though they’re already denied most federally funded programs—his latest move to tamp down on illegal immigration, though it wasn’t immediately clear which initiatives would be impacted.

More than 600,000 immigrant children have crossed the U.S.-Mexico border without a parent or legal guardian since 2019, according to government data.

WASHINGTON - The Trump administration is directing immigration agents to track down hundreds of thousands of migrant children who entered the United States without their parents, expanding the president’s mass deportation effort, according to an internal memo reviewed by Reuters.

There are more than 600,000 migrant children who have crossed the southern border without a legal guardian or parent since 2019, according to government data.

The administration has ousted the head of the government’s deportation force, according to a new report that said President Trump was upset with the slow pace of deportations.

The memo, titled “Unaccompanied Alien Children Joint Initiative Field Implementation,” stated that children would be deported if they have existing deportation orders or served with a notice to appear in immigration court.
