Tapper tried to contradict Pierson’s definition of “bringing a knife to a gun fight” by citing “The Untouchables,” a 1987 mobster movie starring Sean Connery that uses the colloquialism.

He argued that the phrase — typically used to denote entering into a situation unprepared — has a different meaning that Pierson claims.

“I didn’t recognize that, absolutely not,” she responded when Tapper mentioned his assessment based on the film.

“Well, you should check out the film ‘The Untouchables,’” Tapper countered.

Trump cancelled a rally in Chicago last Friday night amid fears that it could provoke widespread violence between protesters and his supporters.

Several of his campaign events have since featured physical conflict between his fans and detractors, with police making multiple arrests across the country.

Trump on Monday denied his public appearances are beset by heated conflicts, arguing that his events have had “no violence” overall. Critics argue that the billionaire’s bombastic rhetoric and hardline policies on issues like immigration are making voter frustrations boil over nationwide.
