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

The Trump administration is powering ahead with efforts to ramp up immigration enforcement, opening up the possibility of targeting migrants who entered through Biden-era programs and invoking an obscure immigration statute to make it easier to deputize state and local law enforcement to arrest and detain immigrants in the U.

The Trump administration gave authorities permission to revoke some migrants' legal status. Meanwhile, White House press secretary Karoline Leavitt posted that President Trump's promised mass deportation operation is now underway on Friday.
