Don't forget that Obama and crooked Hillary along with Eric Holder (who was impeached),  authorized Fast & Furious and they handed over and then "lost" track of thousands of high powered AK firearms that were given to the Mexican drug cartels.  These weapons then were turned on our border patrol officers and they were killed.  These weapons and cartels impacts our sountern borders as illegals pour in and repatriate our money to the elites of Mexico as they take our jobs and act like burros carting in drugs into our country.  
That is why TRUMP is building The Wall.
