Driving the news: The data shows an average of just 13% of nearly 13,000 family members attempting to cross the U.S.-Mexico border were returned to Mexico between March 14 and March 21 using the public health order, which essentially says the U.S. can close the border to nonessential travel because of the coronavirus.

It’s a sign of how the administration is struggling to keep up with a migration surge, and has been recently hamstrung by Mexico’s inability to take in more families the U.S. otherwise would expel.

That doesn’t mean the other 87% percent will remain in the U.S. indefinitely, but they will be allowed into the U.S. to go through immigration proceedings.
