BILL O'REILLY: The hidden headline of illegal immigration is that not one president, not one has even tried to seal the southern border. That's resulted in a massive amount of illegal drugs coming in here as well as undocumented aliens. The reason the Presidents have not secured the border is purely political. The Hispanic American lobby is powerful in the USA and so is big business which for years has used illegal aliens as cheap labor. After 9/11, you would think the federal government would make it a top priority to stop people from coming here illegally because we just don't know who they are. And certainly terrorists have illegally entered the U.S.A. as well as vicious criminals.
