See, right after the meeting, they had a nice speech, said nice things about each other, said that payment of a wall wasn't discussed, etc...
Then after Trump came home to do his speech in Arizona, not only did he say contradictory things about what was discussed at the meeting but President Enrique Pena Nieto did the same thing. He bashed Trump and his wall, stating that Mexico paying for it was not going to happen.
So right now I'm just wondering which one is lying more.
