The fact that Clinton’s staff attempted to destroy her old smartphones whenever they could indicates that they knew there was sensitive information on the devices.

FBI director James Comey revealed in July that Clinton had sent and received emails that were marked classified at the time, and contained information that she and her aides should have known was classified.

Federal law prohibits the unauthorized transfer, storage, or destruction of classified information. Federal records acts likewise prohibit the destruction of government documents, which would have included work-related emails on Clinton’s server and mobile devices.

When old devices containing government documents are to be destroyed, there are precise procedures to be followed, especially if the devices are storing classified information that could endanger national security in the wrong hands.

Presumably, if Clinton’s old smartphones were lost, the information in her emails would be accessible to whoever had found them or obtained them by other means.

Comey indicated that Clinton’s use of private e-mail had indeed posed a risk of being hacked by hostile powers during her travel abroad. Her cell phones certainly would have been a prime target for foreign spies.

However, the documents do note that Clinton said she did not lose a cell phone while traveling.

One report notes that Clinton is known to have used 11 smartphones while Secretary of State, and 2 thereafter. Investigators sought all 13 mobile devices, but two had been destroyed and none of the others could be found.
