U.S. Customs and Border Protection officials announced on Thursday that prototypes for President Donald Trump's proposed border wall with Mexico have been completed.
Now workers will test their mettle using sledgehammers, torches, pickaxes and battery-operated tools.
Results of the testing, which won’t start for at least a month, will dictate future wall construction, which hasn’t yet been funded by Congress.
Two Arizona companies were chosen to build prototypes.
