The number of people arrested for illegally crossing into the U.S. from Mexico dropped for a third month in a row in August, down 62% from the May peak of 132,870 apprehensions, according to government documents reviewed by the Washington Examiner.

A total of 50,693 people were taken into custody at the southwest border during August, the lowest tally since January, when the number rose drastically as tens of thousands of families began arriving each month. U.S. Customs and Border Protection, the parent agency to Border Patrol, is expected to announce the August numbers late this week or early next week.
