How is Trump a populist?

Populism refers to a range of political stances that emphasise the idea of "the people" and often juxtapose this group against "the elite". The term developed in the 19th century and has been applied to various politicians, parties, and movements since that time, although has rarely been chosen as a self-description.

in the U. S. House of Representatives, the Freedom Caucus, which is associated with the Tea Party movement, has been described as right-wing populist. Donald Trump's 2016 presidential campaign, noted for its anti-establishment and anti-illegal immigration rhetoric, was characterized as that of a right-wing populist.
