Migrants allowed into the U.S. temporarily under certain Biden administration programs can be quickly expelled, according to a memo sent by the Trump administration's acting secretary of homeland security.

The Department of Homeland Security is opening the door to the parole status of migrants to be reviewed, leading to their eventual removal from the country.

The Trump administration is empowering federal immigration officers to consider whether to strip temporary legal status from migrants who entered through former President Joe Biden's signature "parole" programs in an effort to ramp up deportations to record levels,

A memo appears to allow Immigration and Customs Enforcement officials to target programs that let in more than a million people.
