The Biden administration is set to restart the Trump administration’s “Remain in Mexico” policy following a court order, according to a Biden administration official.

The policy, which is also known as Migrant Protection Protocols (MPP), started in Dec. 2018 to keep asylum seekers in Mexico while they awaited immigration court proceedings. President Joe Biden revoked the policy soon after taking office.

“In compliance with the court order, we are working to reimplement MPP as promptly as possible,“ Department of Homeland Security spokesperson Marsha Espinosa told Axios.
