Here's What Trump's Border Wall Could Look Like

Funding for President Donald Trump's border wall may be mired in Congress, but along the U.S.-Mexico border, there's been a little more progress.

Eight models of Trump's long-promised border wall, now with an estimated price tag of $1.6 billion, have been erected in San Diego's Otay Mesa outskirts.

Four of the wall models are made of concrete, four of concrete with steel reinforcements, and one is topped with spikes, NPR reports.
