Well.. people from Mexico are coming into America illegally, trafficking, or just coming over to see family and friends. The problem is that our ex president Trump put up walls to keep people from coming into America illegally, they can still come in, but they have to go through a process like getting a green card, etc. some people don’t think what Trump has done because people can’t get into America for free. But some people believe that they shouldn’t come illegally to do stuff like.. said, trafficking.
