Rosen: Tim Kaine, DNC Email Leak Won't Help Hillary's Problems With the Left

Rudy Giuliani appeared on "Sunday Morning Futures" today to react to leaked DNC emails that show an anti-Bernie Sanders bias.

Giuliani agreed with Donald Trump's assertion that this is proof that the Democratic primary was rigged from the start to ensure Hillary Clinton won the nomination.

"This is a rigged system, and Hillary and [Tim] Kaine are right in the middle of the Washington insider rigged system," Giuliani said. "They take money, they take gifts, they take things that ordinary people don't get. And Donald Trump is the guy who's the voice of the outsider."

The former New York City mayor added that many Democratic voters - particularly Sanders supporters - are upset with how the primary played out, which is why he expects this week's Democratic National Convention to be less exciting than the Republican National Convention.
