This bill would create a special fund dedicated to constructing and maintaining physical barriers along the southern U.S. border. It would redirect unspent money from the Coronavirus State and Local Fiscal Recovery Funds, which were part of federal pandemic relief efforts, into this new Southern Border Wall Construction Fund. The Secretary of Homeland Security would control how this money is used for border wall construction and upkeep. The bill does not specify an exact dollar amount or timeline for construction, but instead would transfer whatever unobligated pandemic relief funds remain available. This legislation would affect state and local governments that were expecting to use remaining pandemic recovery funds for other purposes, as those unspent amounts would be redirected to border security instead.
