From the Guardian article:
"The directive, signed by the acting homeland security secretary, Benjamine Huffman, grants Immigration and Customs Enforcement (Ice) officials unprecedented authority to expedite deportations
for immigrants who entered the country with government authorization through two key Biden-era programs.
These programs, which have allowed more than a million immigrants to enter the country since 2023, had provided scheduling for migrants or asylum seekers through
the government-run app CBP One or
temporary legal status for up to two years through a parole program for certain countries."
