Donald Trump, the president of USA, promised the wall in 2016. This wall was built to divide Mexico from America. But why? Mexicans came to America many many times and sometimes they stay there illegally ,so, this is the frist reason to build the wall. Now, the immigration is not controlled, so everyone can bring anything... also drugs. So this is the second reasons to build the wall. But trump also blocks the people who crossed the border just to work so it is a damage for America! The second damage is the cost of the wall that was more than 8,6$bilion dollars. I have finished but now write down what you thing about this wall.
