5:30 PM PT -- Roy Moore has denied Beverly's allegation, going so far as to say he doesn't even know her or know anything about her.
A new accuser of Republican Roy Moore says the U.S. Senate candidate once tried to force her to perform oral sex on him when she was just 16 years old.
Beverly Young Nelson appeared at a press conference Monday in NYC alongside attorney Gloria Allred to make the accusation, tearing up and crying throughout.
Nelson says she was a waitress in Alabama between 1976 and '77, and that Moore -- then the D.A. of their county -- was a regular, and that he would flirt with her. In December of '77, Nelson says Moore signed her yearbook, and then offered a ride home after her shift.
Instead of driving her home, though, she says Moore pulled around behind the restaurant and began groping her breasts, before he allegedly grabbed her neck and tried to force her head toward his crotch.
Nelson says she resisted, and Moore ultimately gave up. She says he kicked her out his car and told her not to tell anyone since no one would believe her.
Moore has also been accused of sexual misconduct with minors by 4 other women. He's been asked by many politicians on both sides of the aisle to step aside.
