United States President Donald Trump is refusing to give up his signature campaign promise of building a wall along the country's border with Mexico.

But Democrats won't give him the more than $5bn he wants to build it.

The stalemate has led to the second-longest partial US government shutdown in history.

In response, Trump went on prime-time television on Tuesday to argue that the barrier is needed to stop what he calls a growing humanitarian and security crisis.

We ask, is there a crisis at the US-Mexico border?
