President Trump should not expect to see a decline in the number of illegal immigrants being apprehended at the southwest border until early fall, despite attempts by the Departments of Homeland Security and Justice to reduce rising levels of border crossings, a Trump administration official said Monday.

The “zero tolerance” policy that Attorney General Jeff Sessions announced five weeks ago will not have an affect on illegal immigration at the U.S.-Mexico border for a “few months,” according to a Justice Department spokesman who spoke with the Washington Examiner and asked to remain anonymous.
