Trump threatens to cancel Mexico summit

President Trump, in two tweets:

"The U.S. has a 60 billion dollar trade deficit with Mexico. It has been a one-sided deal from the beginning of NAFTA with massive numbers... of jobs and companies lost. If Mexico is unwilling to pay for the badly needed wall, then it would be better to cancel the upcoming meeting."

Why this matters: Trump is supposed to meet with Mexican President Enrique Peña Nieto next week to discuss — you guessed it — NAFTA and the border wall. Mexico already threatened to cancel over the question of funding. Now Trump is doing the same.
