As you probably know, Mexican President Enrique Pena Nieto has been asked about paying for President Trump's border wall. His answer was "there's no way." People have debated whether he meant "there's no way" Mexico could pay for such a massive project, or if he was saying "there's no way" they would, but the gist is the same.
Nieto has no intention of paying for a wall.
Trump, on the other hand, has vowed repeatedly that Mexico will fund the project - one way or another. It's been a staple of the Trump campaign since day one, but lately we've been hearing rumblings of budgetary solutions that don't appear to include a whole lot of Mexican money.
