Its the hottest part of the year. Illegal crossings have always dropped significantly in summer, especially in August.
too lazy to look up a chart :)
Either way, the wall and the deal where they have to wait in Mexico will contribute big time I think.
Trump won against Mexico and got what he wanted and it went relatively unreported.
Read the story. The trend is being REVERSED based on previous yrs in the month of August when the summer slow down ends and illegals numbers again increase.
This August they continued to fall.
