From the August 31 edition of CNN's The Situation Room:

WOLF BLITZER (HOST): We're just getting this in from the Reuters News Agency. A spokesman for the Mexican president said, yes, they did speak about the wall, and that Mexico -- the president of the Mexico said -- told Donald Trump very bluntly, “Mexico would not pay for that wall.” You heard Donald Trump said that they spoke about the wall but they didn't talk about who would pay for the wall. So there seems to be a contradiction, a serious contradiction emerging, David, right now.
