President Biden’s administration will comply with an upcoming order from a federal judge in Louisiana that is expected to block the removal of COVID-19 border restrictions.

The restrictions, known as Title 42, are a Trump-era health measure that has been used to deport more than 1 million migrants. The Biden administration had previously planned to end Title 42 on May 23, a move that would have resulted in a surge in illegal immigration.

A Louisiana district court judge has announced plans to block such a move until Biden negotiates a deal with Republican border states. A senior administration official said the White House plans to comply with that order Tuesday, according to Politico.
