SAN DIEGO (AP) - One potential bidder on President Donald Trump's border wall with Mexico wanted to know if authorities would rush to help if workers came under "hostile attack."
Another asked if employees can carry firearms in states with strict gun control laws and if the government would indemnify them for using deadly force.
With bids due Tuesday on the first design contracts, interested companies are preparing for the worst if they get the potentially lucrative job.
A U.S. official with knowledge of the plans who spoke to The Associated Press on condition of anonymity because the details haven't been made public said four to 10 bidders are expected to be chosen to build prototypes.
They will be constructed on a roughly quarter-mile (400-meter) strip of federally-owned land in San Diego
