CNN anchor Wolf Blitzer grilled Donald Trump on Monday over the Republican presidential frontrunner's support from white-supremacist groups.

"Why do you think these various white-supremacist groups are supporting your campaign?" Blitzer asked.

After Trump said that he didn't know anything about the white-supremacist groups that have backed his candidacy, Blitzer told the real-estate mogul about the Anti-Defamation League's list of notable white supremacists who have expressed support for Trump, and pressed him to disavow the groups outright....

During his interview with Trump, Blitzer also raised a number of Trump's recent media firestorms, including his frequent critical tweets about Fox News host Megyn Kelly, violence at his rallies, and an anti-Trump ad showing women reading his past statements about other women's appearances.
