The US military began the delivery of barriers to the southern border earlier in a bid to meet a caravan of thousands of undocumented migrants from Central America said to be making its way across Mexico and toward the United States.
Many Gang Members and some very bad people are mixed into the Caravan heading to our Southern Border. Please go back, you will not be admitted into the United States unless you go through the legal process. This is an invasion of our Country and our Military is waiting for you!
