Lindsey Graham delivered an ominous warning Sunday about a potential prosecution of Donald Trump—he predicted "riots in the streets" if it happens, reports the Hill. What's more, he made the prediction twice. It caught the attention of Trump himself, who posted a video clip of Graham's warning on Fox News during an interview by former GOP congressman Trey Gowdy. In discussing Trump's potential legal trouble over the handling of classified information, Graham made a comparison to Hillary Clinton's use of a private email server when she was secretary of state. The FBI investigated Clinton and called her "careless" but didn't charge her, and the State Department found that while her private server put classified info at risk, investigators found "no persuasive evidence of systemic, deliberate mishandling of classified information," per Insider.
