Is Mexico paying for this?
Yes, they are paying for putting about 20,000 National Guard troops into operation, plus the logistics.
They are really producing results.
Here is the chart the Mexican rep used to brief the US Administration this last week (Tues, 10 Sep). "OTMs" are Other Than Mexicans. Section 235 (B) (2) (c), refers to those under the "Wait in Mexico" policy, who are given court hearing dates, and then sent back to Mexico to wait for them.
With that trend, the flow should reach zero this month, correct?
