What about her emails?

Donald Trump raised that question like a red flag for three years, as candidate and president, casting doubts on how Hillary Clinton used a private email server to communicate with her staff and others while she was secretary of state.

“Hillary set up an illegal server for the obvious purpose of shielding her criminal conduct from public disclosure and exposure, knowing full well that her actions put our national security at risk,” Mr. Trump said late in the campaign.

“Lock her up!” the crowds still chant at his rallies.

Now a three-year State Department investigation has found that, while about three dozen people violated protocols about classified material , they “did their best to implement them in their operations” and “there was no persuasive evidence of systemic, deliberate mishandling of classified information.”

This comes after the F.B.I. determined months before the election that, while Mrs. Clinton was “extremely careless” in having used a private email server for government communications, she did nothing illegal.
