Investigation of Hillary Clinton's private server may net more than just emails

Clinton stands by server use as legally permitted as officials examining system may uncover whether anyone tried to break in and who else had accounts

A forensic examination of Hillary Clinton's private computer server could unearth more details than what she put in her emails. It could answer lingering questions about the security of her system, who had access to it and whether outsiders tried to crack its contents.

Clinton last week handed over to the FBI her private server, which she used to send, receive and store emails during her four years as secretary of state. The bureau is holding the machine in protective custody after the intelligence community's inspector general raised concerns recently that classified information had traversed the system.
