The main problem here is a question of who are these people. Even more, who is helping them, because no way are several thousand people moving without someone providing food and water as well as sanitation. I smell big money here for political optics just in time for our elections.
For everyone who says let them in, can you guarantee that within this hoard are not terrorists from the middle east? Isis has been run out of Syria and Iraq maybe they want to strike back.
As far as I am concerned anyone who provides assistance is engaged in "human trafficking".
Build the Wall! Send the Army! Shut that Border Down!
