'Build that wall' was a regular slogan by US President Donald Trump during and after his campaign.

Now, he's demanding over $5bn from the Democrat-controlled House of Representatives to keep his promise.

The Democrats have refused to give in, leading to a partial government shutdown that began on December 22, affecting nearly 800,000 government employees.

The president has threatened to prolong the shutdown for months or even years.

And there's even talk of declaring a national emergency and bypassing Congress altogether.

So, is this face-off about the wall, or the presidency?

And how is it changing American politics?
