The purpose of this thesis is to examine Donald Trump’s Immigration speech that was held September 1, 2016, in Phoenix, Arizona. The speech was a part of his campaign before he was elected president of America. The focus will be on how Donald Trump represents immigrants and talks about immigration. The research questions are how Donald Trump portrays immigrants and immigration and in what terms immigrants and immigration are argued to be a security risk for the country. The representation of the “Other” and Securitization are the theories that will be applied in the study of the speech. Discourse analysis will be used to find out what his messages are and what his perception of immigration is. The messages are based on the discourses that his language may produce through rhetoric which is the second method. The result of the analysis shows that he takes support from the discourses of “us” and “them”, security and nationalism that is a part of a larger political discourse. Immigrants are rhetorically framed as a security threat by describing them as criminals. He paints the picture of America having an immigration crisis. He mainly uses pathos, as a means of persuasion, to appeal to the audience’s emotions of anger, fear and frustration.
