President-elect Donald Trump has filed an amicus brief in a Texas court urging a federal judge to “immediately stop any ongoing sale of border-barrier materials” until an investigation into the Biden administration’s handling of the border wall is completed, according to a copy of the brief obtained by The Daily Wire.

The brief, authored by attorney John Sauer, who is expected to serve as Trump’s solicitor general in his second term, references The Daily Wire’s exclusive report featuring video evidence of the Biden administration transporting large quantities of border wall materials away from the southern border to be auctioned off to private buyers.

“The outgoing Biden Administration’s reported ‘fire sales’ of border-wall materials to private parties raise grave concerns about the legality of Defendants’ conduct and their compliance with this Court’s permanent injunction in this case,” the brief states. “The Court should order an immediate stop of all such sales and perform a searching examination of the Government’s conduct—by ordering formal discovery if necessary—to ensure compliance with the Constitution, the law, and the Court’s orders.”

A Daily Wire report on December 12 revealed that border wall materials were being transported by private contractors to an auction site, where entire segments of unconstructed wall were being listed with starting bids as low as $5.

During a press conference this week, rump criticized the outgoing administration, stating the current administration is “trying to sell it for five cents on the dollar, knowing we’re getting ready to put it up.”

Steven Cheung, Trump’s top spokesman, said Trump filed the brief because of the Biden administration’s “egregious history of violating the law.”

“Any attempt by Biden officials to obstruct President Trump’s plan to build the Border Wall is unlawful, unconstitutional, and possibly criminal, as our brief argues,” Cheung said. “The Biden Administration has an egregious history of violating the law, especially in its catastrophic open-border policy, so the courts should review their actions here with particular skepticism.”

“President Trump will not be deterred from Building the Wall, securing our border, and Making America Great Again,” he added.

The amicus brief, filed in the Southern District of Texas, pertains to lawsuits brought by Texas and Missouri against the Biden administration over the sale of border wall materials.

The brief argues argues that Trump has made clear his “support for building a system of border barriers at the southwestern border” and that “building the border wall is the clear and emphatic policy of the incoming Trump Administration.”

“Accordingly, President Trump is deeply troubled by recent reports that officials in the Biden Administration have been selling off border-wall materials at rock-bottom prices, especially during this lame-duck period,” the brief further states.

“President Trump has a paramount interest in preventing any unlawful sell-off of border wall materials that may be occurring,” it says. “One of President Trump’s dominant priorities for the next four years—building the border wall—could be unlawfully hampered, delayed, or obstructed by such efforts.”
