It is a good thing our President is going to be re-elected, otherwise these uncompleted border sections would be immediately canceled never to completed. Ever.
The very first segment completed under President Trump (2.25 miles in Calexico, CA) was planned and budgeted under President Bush, but the contract had yet been awarded when Obama was inaugurated.
Upon taking office, Obama/Biden put an immediate halt to any new new contract awards, but allowed already awarded contracts to complete.
