Bill Clinton dismissed repeated attacks by Donald Trump and Bernie Sanders during a rally in North Dakota on Friday. The former president defended his wife Hillary, saying the GOP will do anything to “delegitimize” its opponents.

“I know the Republicans have been mean to her and they say terrible things. You gotta respect ’em — they’re good at this. They delegitimize the people they don’t like. They aren’t in the habit of attacking people they’re not scared of,” Clinton told the crowd at the Fargo, N.D., rally at Rheault Farm.
