James Kallstrom, former head of the FBI’s New York office, is the man who brought to justice the notorious mob boss John Gotti, the Teflon Don.

So when he calls Bill and Hillary Clinton members of a ‘crime family’ it’s fair to assume he knows what he’s talking about.

In a radio interview, Kallstrom described Hillary as a ‘pathological liar’ and said of the couple’s ‘charitable’ Clinton Foundation: ‘It’s like organised crime, really. The foundation is a cesspool.’

Kallstrom says the Clintons should be investigated under the RICO (Racketeer Influenced and Corrupt Organisations) Act, usually reserved for prosecuting the Mafia.

I put ‘charitable’ in inverted commas because only around 10 per cent of the money it receives ends up going to charity. The rest allows the Clintons and their cronies to live like the global super-rich.

When Bill Clinton left the White House after two terms as President in 2001, Hillary complained that they were flat broke. Today they are reported to be worth a staggering $150 million (equal to £120 million at today’s post-Brexit vote exchange rate).

So where’s the money come from? And what did all these mega-donors receive in return? Much of it came from Wall Street banks and malodorous foreign regimes, prepared to pay up to $750,000 (£600,000) for a single speech.

Why would anyone hand over that kind of money for a few political platitudes? What’s in it for them?

That’s what the FBI wants to know, too. Kallstrom has retired but his successors have been conducting two parallel investigations into the Clinton Foundation.

The highest profile operation, which revolved around Hillary’s use of a private email server to send and receive classified correspondence when she was Secretary of State, came to an abrupt halt last night.

The jubilant Clinton camp announced that the matter had been resolved and it was time to ‘move on’. Needless to say, Donald Trump claimed immediately this was further evidence that the system was rigged in favour of Hillary.

But she’s not out of the woods yet, as other inquiries are continuing. While she does seem to have escaped prosecution over use of her private server, there’s still the question of the foundation.

Leona Helmsley, the Manhattan socialite, said famously that taxes are for the little people. That’s how Hillary regards federal law.

Other government employees have lost their jobs and gone to prison for less than she has done. But the Clintons could be heading back to their old Presidential home at 1600 Pennsylvania Avenue, Washington.

When news emerged that she’d been using an unauthorised private server, the FBI issued Hillary with a subpoena to discover what was on it. She responded by immediately deleting 33,000 emails she claimed were ‘personal’ — relating to appointments for yoga classes, arrangements for daughter Chelsea’s wedding, innocuous stuff like that.

Of course they were.

That in itself could be considered a crime, but in the summer the FBI director James Comey declared that while Hillary had sailed close to the wind and behaved extremely recklessly, the bureau wouldn’t be pursuing a criminal prosecution over her use of a private server.

The investigation is widely thought to have been shut down by Attorney General Loretta Lynch, who happened to bump into Bill Clinton for a private chat at an air terminal in Phoenix, Arizona, just as the Department of Justice was considering whether to charge Hillary.

Coincidentally, Lynch owes her big break in law enforcement to Bill, who appointed her as U.S. Attorney in New York when he was President.

Agents who had worked on the Clinton case were said to be furious. Then, ten days before polling day, Comey announced that the investigation was being reopened — this time into emails found on a laptop owned by Anthony Weiner, estranged husband of Hillary’s closest aide Huma Abedin.

The couple are now separated, largely because of Weiner’s incurable habit of sending photos of his genitals to assorted females, one of whom was said to be only 15 years old — which is why the Feds seized his computer.

Somehow, Huma’s correspondence found its way on to her husband’s laptop — possibly including some or all of those allegedly ‘private’ emails Hillary Clinton deleted.

There was fevered speculation that this was the smoking gun which would fire the silver bullet.

Then last night, Comey put out another statement saying that, having reviewed the new evidence, the FBI had not changed its opinion, first expressed in July, that while Mrs Clinton had mishandled classified information it didn’t pass the threshold for criminal charges.

The Clintons are said to be running a cash-for-access scheme — what the Americans call ‘pay for play

But what also emerged last night is that new emails link the Clinton Foundation’s ‘resources’ to Chelsea’s $3 million wedding.

The FBI is under intense pressure to resolve the question of whether this ‘charitable’ organisation is, as their former New York bureau chief insists, a criminal enterprise.

There is compelling evidence —especially in a new best-selling book by investigator Peter Sweizer, called Clinton Cash: The Untold Story Of How And Why Foreign Governments And Businesses Helped Make Bill And Hillary Rich — to support suspicions that the Foundation has been used to launder donations from unsavoury regimes.

The Clintons are said to be running a cash-for-access scheme — what the Americans call ‘pay for play’ — like Tony Blair and Peter Mandelson’s Hinduja passports and Formula One scandals writ large. Hillary is accused of using her office at the State Department to peddle influence and fix lucrative contracts for Bill and his business associates.

In exchange for vast sums of money — such as $12 million (£9.5 million) from Morocco and a $1million (£800,000) ‘birthday present’ to Bill from Qatar — donors were guaranteed a sympathetic ear from not just the Secretary of State but also the woman heavily tipped to be America’s next President.

What’s a few million buckeroos when you get a direct line to the Oval Office?

There have been further claims that Hillary’s private server was hacked by five foreign espionage agencies, putting national security at risk, which if true should instantly disqualify her from running for Commander In Chief.

But it is the rancid stench of corruption surrounding the Clintons which pervades the air. For once, Donald Trump didn’t need to resort to hyperbole when he compared Hillary’s behaviour to the Watergate scandal.

You’d think this story would be dominating the news agenda in the days leading up to tomorrow’s election. But outside of the Murdoch-owned Wall Street Journal and Fox News, which first reported the ongoing FBI investigations into the Foundation, it has been largely ignored by the Clinton cheerleaders in the mainstream media.

I’ve been covering U.S. elections for 25 years and have never seen such partisan Press and television coverage. We moan about the perceived liberal bias of the BBC, but in America most of the media outlets make Pravda look impartial.

Trump claims a net worth of $10 billion (£8 billion), an estimate refuted by those who have examined his finances in detail

Nor have I ever seen two more unsuitable candidates for what is still — or should be —the most powerful office in the world.

Some commentators like to compare this demeaning, divisive election to the House Of Cards TV series, starring Kevin Spacey.

If only. The choice facing American voters is more like a real life House of Horrors. As I wrote here after Super Tuesday in March, when it became obvious that a Clinton-Trump contest was likely: these two deserve each other, but what has America done to deserve either of them?

Trump might call Clinton ‘Crooked Hillary’ and ‘Lying Hillary’ but he’s riddled with serious defects of his own, not least his rampant dishonesty and congenital megalomania.

Trump claims a net worth of $10 billion (£8 billion), an estimate refuted by those who have examined his finances in detail.

He has a record of filing for bankruptcy and even boasts that the fact he doesn’t pay federal income tax only goes to prove how ‘smart’ he is — an insult to tens of millions of low-income Americans who always do the right thing and take paying their taxes seriously.

Trump plays fast and loose with the truth on the stump, making promises he knows he couldn’t possibly keep — such as building a wall along the Mexican border and making Mexico pay for it.

His contemptible references to minorities and his disgusting treatment of women should automatically disqualify him from the race.

Yet even though Trump’s had his fair share of accusations of sexual abuse (the latest involving a former Playboy model), alongside that famously priapic predator Bill Clinton he looks like a paragon of chivalry.

For all Hillary’s protests about Trump’s misogyny, she has been more than happy to help destroy all the women who claim to have been raped by, assaulted by, or had affairs with, her husband. So much for the sisterhood.

I saw a woman driving a car the other day with an anti-Hillary bumper sticker which read: ‘The Devil Wears Pantsuits.’

One thing Hillary is right about is her oft-repeated claim that Trump has neither the character nor temperament to become President. We’re talking pots and kettles here, obviously.

Clinton has never accepted responsibility and will never be forgiven, which helps explain why Trump has been able to run her so close

But one of Trump’s worst traits is his Rizla-thin skin and his knee-jerk retaliation against all and any criticism, real or imagined.

This isn’t someone you’d want with his finger on the nuclear football. Neither is Hillary.

Mrs Clinton makes great play of her ‘experience’, but her record in office is dismal. She was Secretary of State for four years until 2013. On her watch, the world became a more dangerous place.

Having once said she’d nuke Iran to protect Israel, she then supported the deal to bring the mad mullahs back into the fold, by lifting sanctions and allowing them to develop a ‘peaceful’ nuclear programme.

She lied about coming under sniper fire while on a visit to Bosnia. Worst of all, she refused a request to send military reinforcements to protect the American embassy in Benghazi, Libya.

The result was an attack by jihadists on September 11, 2012, in which the U.S ambassador was murdered.

Clinton has never accepted responsibility and will never be forgiven, which helps explain why Trump has been able to run her so close.

Despite all this, if the opinion polls are to be believed — and after Brexit and the 2015 British election that’s a stretch — Hillary’s going to win. But even the so-called ‘experts’ are hedging their bets. Some polls nationally have put Trump in the lead by as much as 5 per cent. It might come down to a couple of states with Florida again pivotal.

Last night Florida was too close to call and has been carpet-bombed with TV ads and rallies by both candidates.

Floridians may have escaped the worst of the impact of the 140-mile-an-hour Hurricane Matthew a couple of weeks ago, but there’s been no escape from Hurricane Hillary and Typhoon Trump.

And even though the polls have narrowed, it still seems likely that the woman Right-wing talk radio host Rush Limbaugh has dubbed ‘The Hilldebeeste’ is poised to become America’s first female president.

If so, she’ll be a lame duck from Day One. Her detractors aren’t going away and neither is the stink surrounding the Clinton Foundation, even though she will use her office to do everything in her power to disrupt and deceive inquiries.

With her feet under the table in the Oval Office, it would be hard to see how the Clintons could be pursued under the RICO anti-corruption Act, as former top G-man James Kallstrom insists they should be.

Pity. It would be delicious to see Bill shuffling into court in his pyjamas every day, pretending to be senile, like those old Mafia godfathers. He looks the part already.

Nothing much has ever stuck to the Clintons. But then again, mob boss John Gotti was called the Teflon Don and the FBI got him in the end.

Republicans hold out the hope that Hillary could yet be impeached for ‘high crimes and misdemeanours’, like her husband over the Monica Lewinsky business.

They’re likely to be disappointed, though. A President can only be impeached for crimes committed while in office. The charges can’t be backdated.

Whoever wins, Americans will be the losers. They’ll just have to grin and bear it for the next four years. Tuesday’s victor will be a one-term incumbent.

The fact that the gruesome charlatan Trump is even in with a shout is to the eternal shame of the Republican Party. Whenever a more credible candidate — such as Florida’s Marco Rubio — got his nose in front during the primaries, they formed a circular firing squad and blasted him to oblivion.

The Donald was Last Man Standing. He didn’t expect to be the chosen nominee and I still find it hard to believe he actually wants the job.
