President Trump tweeted earlier today that he plans to close at least a portion of the U.S-Mexico border next week in an effort to force Mexico to take action and stop the constant caravans of migrants. Because the economic consequences to border closing will be so severe (cross-border trade) it is prudent to provide advanced notice so everyone can prepare:

Something has to change. Doing the same thing repeatedly and not changing the outcome is not a sustainable policy. There is a major ongoing crisis at the border.
