In response to the Biden administration's ongoing auctions of border wall materials, President-elect Trump filed an amicus brief demanding an immediate halt. Claiming the sales, which are said to be at considerable financial loss, threaten to undermine his upcoming policies, Trump argues these actions may violate federal law and could amount to criminal behavior. This legal challenge is supported by the states of Texas and Missouri, who are also seeking judicial examination of the government's conduct regarding the border wall materials. Trump has expressed his intent to resume border wall construction upon taking office.
