A month before Alabama's special election, Republican Senate candidate Roy Moore abruptly faced lurid allegations Thursday of sexual misconduct with minors decades ago — and an immediate backlash from party leaders who demanded he get out of the race if the accusations prove true.

The instant fallout followed a Washington Post report in which an Alabama woman said Moore, then a 32-year-old assistant district attorney, had sexual contact with her when she was 14. Three other women interviewed by the Post said Moore, now 70, approached them when they were between the ages of 16 and 18 and he was in his early 30s. All four women spoke on the record to the Post.

The Moore campaign denied the report as "the very definition of fake news and intentional defamation."

Defiant as ever, Moore himself issued a fundraising appeal asking for emergency donations in a "spiritual battle."

'All-out war on our conservative values'

"I believe you and I have a duty to stand up and fight back against the forces of evil waging an all-out war on our conservative values," he wrote. "I will NEVER GIVE UP the fight!"

Moore, a former Alabama Supreme Court justice, has made his name in Republican politics through his public devotion to hardline Christian conservative positions. He was twice removed from his Supreme Court position, once for disobeying a federal court order to remove a 2,358-kilogram granite Ten Commandments monument from the lobby of the state judicial building, and later for urging state probate judges to defy the U.S. Supreme Court decision that legalized gay marriage.

On Thursday, senior Republicans, including U.S. President Donald Trump, swiftly called for Moore to step aside from the Senate race if the allegations are shown to be true. And the man he defeated in the Republican primary, current Senator Luther Strange, left open the possibility he may re-enter the campaign.

Moore's name cannot be removed from the ballot before the Dec. 12 special election even if he withdraws from the race, according to John Bennett, a spokesperson for the Alabama secretary of state. A write-in campaign remains possible, Bennett added.

Swift and severe reaction

Strange wouldn't immediately say whether he'd re-enter the race.

"Well, that's getting the cart ahead of the horse. But I will have something to say about that. Let me do some more research," he told The Associated Press.

The Alabama special election is to fill the vacancy created when Trump tapped Senator Jeff Sessions to serve as the U.S. attorney general. Then-Gov. Robert Bentley appointed Strange in the interim.

Reaction after the Post story was published online was swift and severe.

The White House said Trump believes Republican Senate candidate Roy Moore "will do the right thing and step aside" if sexual misconduct allegations against him are true. Press secretary Sarah Huckabee Sanders told reporters travelling with Trump in Asia that the president believes a "mere allegation" — especially one from many years ago — shouldn't be allowed to destroy a person's life.

But Sanders said: "The president also believes that if these allegations are true, Judge Moore will do the right thing and step aside."

"The allegations against Alabama Senate candidate Roy Moore are deeply troubling," said Colorado Senator Cory Gardner, who leads the Senate Republican campaign arm. "If these allegations are found to be true, Roy Moore must drop out of the Alabama special Senate election."

Some downplay allegations

Senate Majority Leader Mitch McConnell added, "If these allegations are true, he must step aside."

Texas Senator John Cornyn said, "If it is true I don't think his candidacy is sustainable," and Arizona Senator John McCain also said Moore should step aside.

The intensity of the reaction may partly reflect lingering bad feelings from the primary contest between Strange and Moore, held in late September. Much of the Republican establishment — including McConnell and Trump — supported Strange, while the Republican's more conservative flank — including former Trump strategist Steve Bannon — backed Moore.

Bannon referenced Moore only briefly during an appearance Thursday night in New Hampshire, attacking The Washington Post as an "apparatus of the Democratic Party."

On the ground in Alabama, some Republicans were willing to downplay the allegations.

'Seems like a good guy to me'

"Take Joseph and Mary. Mary was a teenager and Joseph was an adult carpenter. They became parents of Jesus," Alabama state auditor Jim Ziegler told The Washington Examiner.

Moore's Democratic challenger, former U.S. attorney Doug Jones, had little to say aside from an eight-word campaign statement: "Roy Moore needs to answer these serious charges."

In the small eastern Alabama town of Heflin, a handful of people interviewed by the AP indicated they were indifferent to the allegations if not disbelieving of them.

"He seems like a good guy to me," said Pat Hurst, a resident of the town just off Interstate 20 some 120 kilometres east of Birmingham. "I assume everybody has made some kind of mistake in life, but I wouldn't think he needs to step aside unless they prove that he is guilty of some bad sexual conduct."

'I don't believe them at all'

In response to the allegations, Becky Ashley said: "I don't believe them at all. I believe this is Doug Jones, some of his doings, you know. I just don't believe Roy Moore would do that."

"Right now there is a lot of accusations being made against a lot of people," said Randall Mccaffrey. "So I just wonder if it's, you know, maybe these are just the times we are in right now."

The Post reported that Moore, then 32, first approached 14-year-old Leigh Corfman in early 1979 outside a courtroom in Etowah county, Ala. After phone calls and meetings, he drove her to his home some days later and kissed her, the Post quotes Corfman as saying. On a second visit, he took off her shirt and pants and removed his clothes except for his underwear before touching her over her bra and underpants, Corfman told the Post. He also guided her hand to touch him over his underwear, she said.

"I wanted it over with — I wanted out," she told the Post. "Please just get this over with. Whatever this is, just get it over."

Alabama law lists the legal age of consent as 16.

The state's statute of limitations for bringing felony charges involving sexual abuse of a minor in 1979 would have run out three years later. Corfman never filed a police report or a civil suit, the Post said.

None of the other women said that Moore forced them into any sort of relationship or sexual contact.
