The state of Texas is seeking a permanent block for a new Biden administration rule that allows more asylum seekers to avoid deportation at the border, according to a Thursday lawsuit obtained by Fox News Digital.

Texas Attorney General Ken Paxton filed the lawsuit Thursday, naming Homeland Security Secretary Alejandro Mayorkas and President Biden, among others, as defendants.

The suit seeks to block a DHS policy that seeks to change the processing system for immigrants who claim “credible fear” of persecution in their home countries. Current law states that immigration judges handle such cases, but the DHS rule, which would take effect May 29, transfers that authority to asylum officers.
