US/Mexico: Trump threatens to close border March 29

Event

US President Donald Trump threatened to close "large portions" of the US-Mexico border on Friday, March 29. In a series of tweets, Trump said that he would close the border "next week" if Mexico didn't curb all illegal border crossings. It is unclear whether what, if any, measures would go into effect. Official ports of entry would likely be the most affected in the event of any adjustments to the status of the border; increased security or partial checkpoint closures may result in congestion and wait times for processing people or goods crossing the border.

Context

Trump has previously threatened to close the US-Mexico border though no such closures have gone into effect. 

Advice

Individuals traveling overland across the US-Mexico border are advised to monitor developments to the situation.
