Which phrase from the article trumps inauguration you understand what the author means by divided

When he starts to talk about immigrants and how he wants to stop them. 

A division is a separation of something and one of the things that Donald Trump wants to separate from our country is illegal immigrants, which is why he promotes so strongly of building a wall. The wall will protect immigrants that have come to the United States legally as well as protecting the United States citizens who are here and are getting their jobs taken by illegal workers, whom are willing to work for much cheaper than most of us.
