His campaign in turmoil, Donald Trump on Thursday launched an all-out counterattack against the women who have accused him of sexual harassment and assault — calling them “horrible, horrible liars.”

“These claims are all fabricated. They’re pure fiction and outright lies,” Trump said at a rally in West Palm Beach, Fla.

He blasted the media for giving credence to the claims — which he insisted are part of “a concerted, coordinated and vicious attack” on him.

“It’s no coincidence that these attacks come at the exact same moment, and all together at the same time as WikiLeaks releases documents exposing the massive international corruption of the Clinton machine,” Trump said.

Some of the shocking things Trump has said about women:

The GOP presidential candidate claimed he has “substantial evidence” to disprove the accusations against him, which he will disclose “in an appropriate way and at an appropriate time.”

At least six women have now accused Trump of inappropriate conduct — including a People magazine writer who said he tried to force his tongue down her throat during an interview at his Mar-a-Lago resort in 2005.

“Look at her. Look at her words. Tell me what you think. I don’t think so,” Trump said at the rally.

He claimed there were “no witnesses” to the alleged sexual assault and the two were standing in a room with glass walls.

In a tweet, Trump called a New York Times story detailing claims from two women who say he abused him “a total fabrication.”

A “high-ranking” campaign official told CNN that “NYT editors, reporters, politically motived accusers better lawyer up.”

Democratic operative David Brock and lawyer Gloria Allred both said they’re willing to pay for the legal defense of any of Trump’s accusers.

In other developments:

Trump canceled an appearance on Sean Hannity’s Fox News show that was scheduled for Thursday evening.

The Times said it will not retract the article about the sexual-harassment allegations against Trump. “We welcome the opportunity to have a court set [Trump] straight,” the paper’s lawyer, David McCraw, wrote in a letter to Trump attorney Marc Kasowitz.

At a Clinton rally at Southern New Hampshire University, Michelle Obama ripped into the billionaire, saying his boasts about groping women have, “shaken me to my core in a way that I couldn’t have predicted.”

The soap-opera star who greeted Trump in 2005 moments after he boasted to “Access Hollywood’s” Billy Bush about how his fame gave him license to grope women spoke out for the first time Thursday, calling his comments “offensive” but ”not shocking.” “They are offensive comments for women. Period,” “Days of Our Lives” star Arianne Zucker told NBC’s “Today” show.

One Trump adviser told Bloomberg News that the candidtate intends to go “buck wild” on Clinton for her husband’s infidelities. Trump campaign manager Steve Bannon went a step further — saying the goal is to “turn [Bill Clinton] into Bill Cosby.”
