There’s been a lot of talk recently about sexual assault and presidential candidates.

Democratic presidential candidate Hillary Clinton’s campaign has let all sorts of accusations fly at GOP rival Donald Trump — but there’s one bombshell Clinton probably wasn’t expecting.

A new book is raising questions about former President Bill Clinton’s already sleazy sex history — and if true, these allegations could TOTALLY shake up the 2016 presidential campaign.

Bill Clinton’s disgusting past as a sexual predator is back in the limelight in a book released Monday by bestselling author James Patterson.

Patterson’s book, “Filthy Rich,” chronicles the pedophilia and sexual assault allegations against billionaire Jeffrey Epstein and his oddly close friendship with Clinton.

The “Lolita Express” was Epstein’s private jet. Clinton had taken at least 10 flights on the Lolita between 2001 and 2003, suspiciously foregoing Secret Service detail at least five of those flights, Fox news reported.

This jet soon became infamously known as one of Epstein’s favorite locations to take advantage of underage girls, and Clinton’s request to fly solo became much more suspicious, Patterson says.

Sponsored: Strange “instant pain relief” secret caught on video

Have you seen the weird “little brown bottle” video?

In the short video, you can see how more than 535,311 people have discovered an underground sensation in pain relief — with NO mass media advertising. Some people are saying that just one or two drops of a clear substance relieved their pain instantly — and for hours or DAYS.

If you or a loved one is suffering from arthritis, shoulder, hip, or joint pain you MUST see this brief viral video. It will only take a moment, and your pain could finally be gone.

In fact, the little brown bottle is a nightmare for those highly paid “Pain Specialist” MDs. So I wouldn’t be surprised if they tried to get the video banned or discredited. While it’s up there, watch it now.

This isn’t a fringe lunatic writing this, either. Patterson is one of the best-known authors in America, and the 300-page non-fiction novel has an original print run of 500,000 copies and is predicted to be a best seller.

It describes the close relationship between the two powerful men, and the injustice of the alarmingly short, 13-month sentence Epstein received following his disgusting sexual escapades and abuse accusations.

Patterson describes Epstein’s case as a “year long assault” on prosecutors, alleging they were biased and weren’t fit to be on the case. His victims attempted to appeal the leniency of the sentence, but consistently failed.

Epstein owned a private island that famously became known as “orgy island,” a place that Clinton visited numerous times between 2002 and 2005, according to the Daily Mail.

The two were such close friends, that Epstein had the former president’s email addresses and multiple phone numbers. Clinton praised Epstein for his “insights and generosity,” and legal documents revealed that Clinton owed ‘favors’ to Epstein.

Epstein even claimed to be a co-founder of the Clinton Foundation in his plea deal and received a lesser sentence for operating a sex ring with underage girls due to his charitable work with Clinton’s family foundation.
