BIRMINGHAM, Ala. -- Ever defiant, Republican Roy Moore's chief backers invoked the Bible in lashing out at the women accusing him of sexual misconduct. Women's advocates decried the talk as worn intimidation tactics in a desperate attempt to keep his imperiled Senate bid alive.

Moore ignored mounting calls from Washington Republicans concerned that if he stays in the race he may not only lose a seat they were sure to win but also may do significant damage to the party's brand among women nationwide as they prepared for a difficult midterm election season.

Moore appeared Thursday alongside more than a dozen religious leaders, who took turns bashing the Christian conservative's many critics -- especially his female accusers.

"This is a man who does not lie. Compare that to his accusers," charged Gordon Klingenschmitt of the group Pray in Jesus' Name.

With Moore looking on, Klingenschmitt quoted the Ten Commandments in a message aimed at two women he called out by name -- one has said she was 14 and the other that she was 16 when Moore initiated sexual contact as a district attorney in his 30s.

"Thou shalt not bear false witness," Klingenschmitt declared.

Moore called the allegations "unsubstantiated," "unproven" and "fake."

"They're not only untrue, but they have no evidence to support them," he insisted, refusing to answer any questions from reporters about the allegations.

Emotions ran high for some Moore supporters. Following an appearance by more than a dozen evangelicals who spoke on stage in support of Moore, some shouted down journalists who attempted to ask Moore about the women's accusations.

"You are the fake, lying news from the swamp!" yelled one woman. Flip Benham grabbed the camera of an Associated Press journalist and repeatedly said: "Did you stop beating your wife, yes or no?"

President Donald Trump, through a spokeswoman, called the allegations of sexual misconduct against the former judge "very troubling." The Republican president stopped short of calling on Moore to quit the race, however, breaking with most Republican leaders in Washington, including McConnell, the Senate majority leader.

"He thinks that the people of Alabama should make the decision on who their next senator should be," White House press secretary Sarah Huckabee Sanders said, declining to clarify whether Trump continued to back Moore.

Trump did take time to publicly ridicule Democratic Sen. Al Franken, who apologized Thursday after a woman who had travelled with him on a USO tour in 2006 accused him of forcibly kissing her and then groping her for a photograph taken while she was sleeping on a transport plane. Trump tweeted that the photo was "really bad" and that "just last week he was lecturing anyone who would listen about sexual harassment and respect for women."

Moore has given a single media interview about the allegations to Fox News Channel host Sean Hannity. His campaign website has added a form asking people to report "inappropriate news organization contact."

Still, he has repeatedly hinted that his team has gathered evidence against his critics. He cited evidence of "collusion" soon after the initial report surfaced last week.

His wife circulated a fake report earlier in the week that reporters were offering to pay thousands of dollars for women to come forward with new claims against Moore. In a subsequent social media post, she described the media's actions as "an all-out assault, which is why we are suing them."

"You ask me if I believe the girls. No, I don't believe the girls. I believe Judge Moore," Moore strategist Dean Young said. "Let the battle begin. ... Get ready to fight Mitch McConnell. We're going to fight you to the death on this."

Moore's attorney has demanded that one of the accusers, Beverly Young Nelson, release a yearbook she contends Moore signed so it can be analyzed by a handwriting expert to prove its authenticity. Nelson says that Moore aggressively groped her in a locked car when she was 16.

The Moore campaign dug up Nelson's divorce papers, which had been signed by Moore, and held them up to cameras suggesting she had copied the signature.

It was unclear whether the campaign was taking other steps to probe the background of his accusers. Moore strategist Dean Young said "no" when asked Thursday whether the campaign had hired a private investigator.

Gloria Allred, Nelson's attorney, said she and her client were prepared for Moore's "slash and burn" approach.

"If in fact his attempt is to intimidate her or me, he has failed miserably," she said. "We prepared. We knew that this would be a battle for the truth, that this is someone who most likely will fight to the end."
