President Biden on his first day in office suspended construction of the border wall pending a review of its legality. The next day the Department of Homeland Security (DHS) suspended Trump's "remain in Mexico" policy, which blocked migrants from crossing the border to apply for asylum.
The order places the cases in abeyance, essentially pausing litigation while the Biden administration reviews the legality of each policy and develops their own.
The border wall case was brought by the American Civil Liberties Union (ACLU), the Sierra Club and others and challenges $2.5 billion in Department of Defense spending that was diverted to complete construction. The administration wrote to the court Monday:
"The President has directed the Executive Branch to undertake an assessment of 'the legality of the funding and contracting methods used to construct the wall'. It would therefore be appropriate for the court to hold further proceedings in this case in abeyance to allow for the completion of the process that the president has directed."
Comment: Biden's plan: Tear down the US/Mexico border wall, but surround the US Capitol with barbed wire fencing.
