Donald Trump became the 45th president of the United States in large part by campaigning against the establishment.

Now, author and conservative pundit Nick Adams says, the establishment is fighting back.

A Fox News regular, Adams is a native Australian and former deputy mayor of Sydney now fully at home in Trump’s America. What he sees here, he says, is a country beset by an ideological civil war between an anti-Trump establishment and those – including himself – embracing the president’s agenda.

Adams, also a commentator on the Fox Business Network and founder and executive director of the Foundation for Liberty and American Greatness, examines that schism and struggle in a discussion of his latest book, The Case Against the Establishment, co-written with social commentator Dave Erickson.
