WASHINGTON (WPVI) -- Roy Moore's support from fellow Republicans is hemorrhaging after a second woman accused the Alabaman of groping her when she was a teenager in the late 1970s, the latest setback to his effort to win an open Senate seat that suddenly seems up for grabs.
"I can tell you without hesitation this is absolutely false," Moore said Monday at an abruptly called news conference in Gallant, Alabama, after the latest allegations were made. "I never did what she said I did. I don't even know the woman."
The former state Supreme Court judge and outspoken Christian conservative spoke after a tearful Beverly Young Nelson, now 56, detailed new allegations to reporters in an emotional appearance in New York.
One night when she was 16, Moore offered to drive her home from her after-school job at a restaurant in Gadsden, Alabama, she said. Moore, a regular customer, instead parked behind the restaurant and locked the door to keep her inside, squeezing her neck while trying to push her head toward his crotch and trying to pull her shirt off, Nelson said.
"I thought that he was going to rape me," she said.
Moore stopped and as she left the car he warned no one would believe her because he was a county prosecutor, Nelson said. She said her neck was "black and blue and purple" the next morning.
Even before Nelson's news conference, Senate Majority Leader Mitch McConnell took a remarkably personal swipe at Moore, based on last week's Washington Post reports of other incidents involving Moore and teen-age girls decades ago.
"I believe the women," said McConnell, R-Ky., marking an intensified effort by leaders to ditch Moore before a Dec. 12 special election that has swung from an assured GOP victory to one that Democrats could conceivably swipe.
Moore fired back at McConnell on Twitter.
"The person who should step aside is @SenateMajLdr Mitch McConnell. He has failed conservatives and must be replaced. #DrainTheSwamp," Moore wrote.
He also signaled he has no intention of ending his candidacy, writing in a fundraising appeal, "I'd be honored to have you in my corner with me while I slug it out with the forces of evil trying to keep me out of Washington."
The exchange between McConnell and Moore underscored the civil war between establishment Republicans worried that candidates like Moore could cost them their Senate majority and hard-right elements who say McConnell is not conservative enough.
Moore has been backed by Steven Bannon, President Donald Trump's former chief White House adviser who is openly seeking GOP Senate challengers who will pledge to dump McConnell. A political committee linked to McConnell spent huge sums unsuccessfully trying to defeat Moore in the GOP's September primary, but Moore defeated incumbent GOP Sen. Luther Strange.
Republicans have discussed having another Republican like Strange stage a write-in candidacy, but Strange told reporters Monday "a write-in candidacy is highly unlikely."
"I made my case during the election," Strange said.
McConnell, who last week said Moore should stand down if the allegations were true, was joined by other Republicans who intensified their opposition to him.
No. 2 Senate GOP leader John Cornyn and his Texas Republican colleague, Sen. Ted Cruz, both withdrew their endorsements of Moore. Cory Gardner of Colorado, who heads the Senate GOP's campaign organization, said if Moore is elected, senators should expel him "because he does not meet the ethical and moral requirements" of the Senate.
Sen. John McCain, R-Ariz., said Moore "should not be a United States senator, no matter what it takes." Sen. Jeff Flake, R-Ariz., who's not seeking re-election after criticizing Trump, said he'd "vote for the Democrat" if he had to choose between Moore and Democrat Doug Jones.
Last week, The Washington Post reported that in 1979 when he was 32, Moore had sexual contact with a 14-year-old girl and pursued romantic relationships with three other teenage girls around the same period. The women made their allegations on the record and the Post cited two dozen other sources.
Moore denied last week molesting the 14-year-old but didn't flatly deny he'd dated teenagers, saying in an interview with conservative talk show host Sean Hannity, "It would have been out of my customary behavior."
Nelson said that before the alleged incident that Moore signed her yearbook. A copy of her statement at the news conference included a picture of what she said was his signature and a message saying, "To a sweeter more beautiful girl I could not say, 'Merry Christmas.'"
The tumult comes with Republicans holding a scant 52-48 Senate majority as the GOP rushes to push a massive tax cut through Congress by Christmas. Facing near-certain unanimous opposition by Democrats, Republicans can lose just two GOP senators, and a Democratic pickup in Alabama would narrow their margin of error to one.
Yet a Moore victory would open the party to relentless Democratic attacks in next year's elections.
Jones' campaign released a statement Monday saying: "We applaud the courage of these women. Roy Moore will be held accountable by the people of Alabama for his actions."
