Worcester Delegate On Why He's Supporting Donald Trump

Bill McCarthy, a Republican National Convention delegate from Worcester, has been a Donald Trump supporter from the start. McCarthy is a former Connecticut state trooper and now teaches criminal justice at Quinsigamond Community College.

This is the first time he's attended a convention. One theme of the event is "Make America Safe Again" — something that strikes a chord with McCarthy. He's worried about immigration and its effects on national security. He joined WBUR's All Things Considered to discuss those concerns and his support for Trump.
