[WASHINGTON] Donald Trump on Thursday savaged US media for reporting claims that he groped and forcibly kissed women - allegations he said were "outright lies" - as First Lady Michelle Obama blasted the Republican nominee in a campaign trail tirade.
With just 26 days until Americans go to the polls to choose a successor to her husband on Nov 8, a visibly angry Mrs Obama delivered a fiery takedown of the real estate mogul and his "disgraceful" behavior.
"Now is the time for all of us to stand up and say, enough is enough," Mrs Obama told a rally for Hillary Clinton in New Hampshire.
"This has got to stop right now."
But the 70-year-old billionaire was not cowed, castigating his accusers as "horrible liars" and decrying his Democratic rival as a criminal complicit in a coordinated media attempt to sabotage his campaign.
Claims by at least six women have come to light in accounts reported by The New York Times, NBC, People Magazine and other outlets, most of them after Mr Trump asserted in Sunday's debate with Mrs Clinton that he never sexually assaulted women.
Mr Trump's accusers countered that statement, saying he made unwanted physical advances against them.
With his campaign in free-fall, Mr Trump lashed out in swing state Florida with a venomous speech in which he denied the alleged incidents took place.
"These vicious claims about me of inappropriate conduct with women are totally and absolutely false. And the Clintons know it very well," Mr Trump told a rally in West Palm Beach.
"They're pure fiction. And they're outright lies."
The attacks, he added, "are orchestrated by the Clintons and their media allies".
Mr Trump said his lawyers were preparing a lawsuit against The New York Times, which published the accounts of two women who accused him of groping and kissing them, unless the paper retracts the article.
The Times refused to back down.
"We published newsworthy information about a subject of deep public concern," the paper's assistant general counsel David McCraw said in a letter to Mr Trump's lawyers.
"If Mr Trump disagrees, if he believes that American citizens had no right to hear what these women had to say and that the law of this country forces us and those who would dare to criticise him to stand silent or be punished, we welcome the opportunity to have a court set him straight."
The women's claims surfaced just days after a video emerged of Mr Trump boasting in 2005 that his fame allowed him to grope women with impunity, sending the White House race into unprecedented levels of vulgarity.
He has apologised and, trying to reverse his deficit in national polls to the 68-year-old Mrs Clinton, has sought to minimise the comments as "locker room talk" - a remark that went too far for the first lady.
"This wasn't locker room banter. This was a powerful individual speaking freely and openly about sexually predatory behaviour. And actually bragging about kissing and groping women," said Mrs Obama, 52.
"It doesn't matter what party you belong to... no woman deserves to be treated this way. No one deserves this kind of abuse," she said.
"This is not normal. It is not politics as usual. This is disgraceful. It is intolerable." The allegations against Mr Trump suggest a decades-long pattern of sexually inappropriate behaviour.
Jessica Leeds, a 74-year-old former businesswoman, told the Times that Mr Trump groped her on a flight in the early 1980s as they sat next to each other in first class, grabbing her breasts and trying to put his hand up her skirt.
"He was like an octopus," Ms Leeds said.
"His hands were everywhere," she added. "It was an assault."
A second accuser, Rachel Crooks, said she was a 22-year-old receptionist at a real estate company in Trump Tower in 2005 when she encountered Mr Trump outside an elevator.
After she introduced herself, he "kissed me directly on the mouth," she told the Times.
A photographer's assistant alleged that Mr Trump grabbed her rear end at his Mar-a-Lago estate in Florida in 2003, while a former staff writer for People accused Mr Trump of forcibly kissing her during an interview there in 2005.
"Trump shut the door behind us," Natasha Stoynoff wrote.
"I turned around, and within seconds he was pushing me against the wall and forcing his tongue down my throat." Mr Trump dismissed the Stoynoff account out of hand.
"People all over the place," he said.
"Look at her, look at her words. You tell me what you think. I don't think so."
Two beauty pageant contestants also accused Mr Trump of either groping or forcibly kissing them.
As the White House campaign entered its brutal last stretch, Mr Trump had repeatedly threatened to damage Mrs Clinton by reviving allegations of sexual misconduct by her husband.
He made good on that promise by appearing with three of Bill Clinton's women accusers ahead of Sunday's debate, and alleging on stage that the former president was "abusive". He also went nuclear about Mrs Clinton and her economic policies Thursday, charging that the former secretary of state met "in secret with international banks to plot the destruction of US sovereignty in order to enrich these global financial powers."
Mrs Clinton, visiting a campaign field office in San Francisco, briefly addressed the ugliness of the White House race.
"We cannot let this pessimism, this dark and divisive and dangerous vision of America, take hold in anybody's heart," she said.
"It's more than just the way he degrades women, as horrible as that is. He has attacked immigrants, African Americans, Latinos, people with disabilities, POWs, Muslims, and our military, which he's called a disaster. There's hardly any part of America that he's not targeted."
