John Oliver Attacks Donald Trump's Mexico Border Wall On 'Last Week Tonight'

Surprisingly, Donald Trump has no idea what he's talking about.

Ever since walking racism machine Donald Trump announced his presidency and plunged us into some sort of dystopian hellscape timeline, he hasn't really been clear on any policies except one - he wants to build a bloody massive wall on the border of the US and Mexico.

This is a big problem, and as John Oliver has expertly shown, it just gets bigger as it unravels.

Thanks to a little bit of digging, John has found that Trump's little idea will cost big, big bucks and will essentially be a financial black hole.

In addition to that, it probably won't even make a difference. Great.
