Donald Trump promises US-Mexico border wall: 'Walls work - ask Israel'
Billionaire Republican primaries candidate Donald Trump has promised to build a wall along the US-Mexico border.
"People who live in Mexico and Asia are coming here to give birth to babies so that we will have to be responsible for them for the next 85 years," Trump said at a press conference in New York. "People will come to the US, but by legal means. Walls work - ask Israel."
