A policy adviser on Donald Trump’s campaign says Republicans have two options: support Trump as the G-O-P’s presidential nominee or just “shut up.”

Sam Clovis from Sioux City says Trump is winning because he has the support of  ordinary Americans

Clovis says Trump’s Republican critics aren’t seeing what Trump is really like

Clovis took a leave from his job as a professor at Morningside College to join Trump’s campaign team last August
