Politics is the art of social and government affairs for the common good. The origins of politics go back to the early stages of human organization (tribes and lineages). However, only after the emergence of political communities did higher forms of political activity and relations between government and the stock emerge, as well as political relations between states as an external political plan. Communication is the exchange of information, ideas and feelings, through verbal and non-verbal means which are tailored to the social nature of the situation. Unlike "ordinary" communication, political communication has a predominantly persuasive function. Discourse is a series of statements that have a certain meaning and influence in a social context. There are two basic forms of political speech. The first is the authoritative speech depicting authority and power. The second form has been present since the French Civil Revolution and is based on the people’s right to vote. Euphemisms are linguistic forms, words, and expressions used in communication to alter undesirable and inappropriate expressions that point to an interlocutor and establish an unpleasant association. These may also be a sign of political correctness and manipulation (distortion, forgery, or overlapping of true truth). Public relations is a profession that incorporates communication functions, media relations, crisis management and public speaking. The paper analyzes certain speech of the former US President George W. Bush and the speech of the incumbent President Donald Trump. In their speeches, Bush focuses on terrorism whereas Trump’s main focus is on immigration issues. Both presidents create and use euphemisms through similar, and partly the same, mechanisms.
