WASHINGTON (AP) — A new Biden administration rule announced Thursday aims to speed up asylum processing at the southern border, enabling it to quickly reject a limited group of people believed to have committed serious crimes or who have terrorist links.

The change comes as the administration has been struggling to demonstrate to voters during an election where immigration is a key issue that it has a handle on the southern border. Republicans have consistently slammed the Biden administration over policies that they say have worsened problems at the southern border.

In a statement announcing the changes, the Department of Homeland Security said migrants who are deemed to pose a public threat are taken into custody but a determination on whether they’re eligible for asylum isn’t made until later in the asylum process. Under the proposed rule, asylum officers hearing cases at an initial screening stage that happens just days after a person arrives in the country will now be able to consider that criminal history or terrorist links when deciding whether someone should ultimately be removed from the country.
