Long before Donald Trump became President, he stated over and over during his campaign that Mexico would be paying for the USA/Mexico border wall and that US taxpayers would be paying nothing

After being elected, Trump changed his story

Not only would Mexico not be paying for the wall, but US taxpayers would be footing the bill instead
