Weiner was even impervious to the stench emanating from the Bitch-of-Benghazi

The simple, direct answer is the Weiner kept an "insurance policy".

Occam's Weiner

Happy Halloweiner, the night when Anthony Weiner's undead penis rises from its grave to bite Hillary's campaign. The stroking dead is apparently impervious to silver bullets or garlic, and unlike vampires it does show up in photographs, on cell phones across the globe.
So in the final week of the campaign the plot twists arrange themselves in a remarkably straightforward manner. The FBI is investigating the Clinton Foundation - because it's a criminal enterprise: if you give a million bucks to the the Clintons' charity, sixty grand goes to charity and the remaining 940,000 goes to fund the lifestyles of Bill, Hillary, Chelsea and their various malodorous associates - Sid Blumenthal, Terry McAuliffe, etc.
For four years, however, those donations also bought you access to the US Secretary of State. That's why Mrs Clinton and her coterie - Huma Abedin, Cheryl Mills, and the other supposed "government employees" - determined to use a private server. Because the pay-for-play was so unsubtle you couldn't have it sitting on State Department emails destined for the National Archives.

We now learn that the FBI are looking into 650,000 emails discovered on Anthony Weiner's laptop, a machine Huma Abedin has told friends she never used - as you wouldn't, if your spouse had the habits Mr Weiner has.
