The FBI is recommending that Hillary Clinton, the presumptive Democratic presidential nominee, should not be indicted over the use of a private email server.
"No reasonable prosecutor would bring such a case," Comey told reporters.

Comey said 110 emails sent or received on the Clinton server contained classified information. He also said it's possible "hostile actors" gained access to the server.
