To authorize the transfer to Arizona, New Mexico, and Texas of certain materials for the construction of the border wall, and for other purposes.

This bill authorizes the transfer of unused materials from previous border wall construction funding to Arizona, New Mexico, and Texas. It allows the Homeland Security Secretary and Army Chief of Engineers to move these materials without new appropriations. The materials were originally allocated for border wall construction in those states but remain unused as of the bill's enactment. The bill specifically targets existing, unspent resources to support ongoing or future border wall projects in the three states.
