Sources told Fox that the situation there is getting worse every day and the numbers are growing by the hour. 

A DHS source told Fox News that there were 208,887 encounters in August. While it marks the first decrease in migrant encounters seen under the Biden administration, during which migrant encounters have been sharply rising for months, it is only a 2% drop over the more than 212,000 encounters in July.

The 208,887 number for August represents a 317% increase over August 2020, which saw 50,014 encounters — and a 233% increase over August 2019, where there were 62,707 amid that year's border crisis.
