US President Donald Trump's top homeland security official has signed two orders that could expand the number of undocumented immigrants who could be stopped and deported, according to documents seen by Reuters and first reported by McClatchy News.
Department of Homeland Security Secretary John Kelly included the new orders in two memos signed on Friday, but the memos have yet to be cleared by the White House, two sources told Reuters on Saturday.
The orders were guidance to follow executive orders Trump signed on January 25.
Under the orders, hundreds of thousands of people would face expedited removal proceedings, including those previously not prioritised for deportation under former President Barack Obama.
Those people include those who were charged with but not convicted of crime and parents of children who entered the United States illegally.
Kelly said in one of the memos that illegal immigration across the US border with Mexico had "created a significant national security vulnerability to the United States".
The memos also instruct the agencies to recruit police and sheriff deputies to assist immigration agents.
