The FBI has always been dirty — consider local G-men Zip Connolly and H. Paul Rico, who were both Mob hitmen, not to mention John “Vino” Morris and a host of other very “special” agents in the Boston office.

Still, the Famous But Incompetent crew has never been as corrupt as it is now shown to be.

The Uranium One Clinton bribery scandal and the dodgy dossier are Watergate on steroids.

That so-called dossier — a remake of “From Russia with Love.” Commissioned and paid for by Hillary Clinton and the Democratic National Committee, it’s 35 pages of fabrications about the Republican candidate for president, breathlessly peddled for months by the Democratic operatives of the alt-left media. When Hillary stopped paying for it, the G-men stepped in as paymasters. They saw it as part of their job — to fix the election.

The FBI was going to use taxpayer funds to buy agitprop from Russia to undermine the one candidate whose spouse hadn’t collected $500,000 cash from the Kremlin. Talk about collusion.

It gets worse. The dossier’s “unverified and salacious” allegations, in the words of bent former FBI director James Comey, may have been used to get warrants to surveil Trump and his associates. And they said Nixon was into dirty tricks?

If a cop lies to obtain a warrant, whatever evidence he collects from that warrant is thrown out of court. They call it fruit of the poisoned tree. What allegations in the dirty dossier have ever panned out? Now the card-carrying Hillary apologists are claiming it was just “opposition research,” but there’s no real research in it.

The best spin the Democrats can put on the dossier is that the most serious fabrications in the dossier “remain unproven” or “uncorroborated.”

And if the dossier were really on the level, then why did Hillary and the DNC adamantly deny for a year, sanctimoniously, as The New York Times put it, and sometimes in front of congressional committees, that they had paid for the anti-Trump smear campaign. They lied, for a year, over and over and over again. Just ask the Times reporters.

The fake-news dossier was released in January by BuzzFeed, a cat-video website owned by NBC News. You know, the outfit of Chelsea Clinton, the Rev. Al Sharpton, Brian Williams and Mike Barnicle. NBC News killed Ronan Farrow’s expose on Harvey Weinstein, one of the Clintons’ biggest campaign contributors.

Naturally the alt-left media, now that a scandal seems likely to afflict Democrats, has lost interest in it.

Three months ago, these Democrat hacks were literally accusing Donald Trump Jr. of treason for a 10-minute meeting with a Russian lawyer. Now it turns out that the Democrats funneled $9.2 million to a law firm that then worked with Russians to sabotage the presidential election, and all they can say is, “Everybody does it.”
