Hillary Clinton is not playing Trump’s game of making her deny his false allegations. He wants her to play on defense. But I will.

Donald Trump stated the following:

“She made 13 phones disappear, some with a hammer.”

Factcheck.org disagrees:
It is true that the FBI said (on page 8) it “identified 13 total mobile devices … which potentially were used to send e-mails using Clinton’s clintonemail.com e-mail addresses.” But only eight of the 13 were used while Clinton was secretary of state, the FBI said, so Trump exaggerates the number of devices she had during her four years in office. (See “A Guide to Clinton’s Emails.”)
The FBI also quoted a Clinton aide (on page 9) as saying that he could recall on two occasions that he got rid of old mobile devices by breaking them in half or hitting them with a hammer.
Trump insinuates that there is something sinister about owning several mobile devices and destroying the old ones when they are replaced. But the FBI came to no such conclusion, and security experts interviewed by the technology website Wired said destroying old devices is a good way to erase data — if done properly.
