Donald Trump will do it! He will not stand back from building the great wall on the southern border to stop the illegal immigration. Wednesday night he is going to make an immigration speach in Arizona and reveal the solution of immigration problem.
From day one I said that I was going to build a great wall on the SOUTHERN BORDER, and much more. Stop illegal immigration. Watch Wednesday!
