Alabama Republican Senate candidate Roy Moore reportedly claimed the reason his accuser won't hand over a yearbook that she maintains is evidence he engaged in sexual misconduct four decades ago was because the allegations were "completely untrue," The Hill reported Saturday.

"What they have alleged is completely untrue," Moore told Aaron Klein in an interview on New York's AM 970 "The Answer" set to air Sunday.

Gloria Allred, attorney for the accuser, Beverly Young, had offered to hand over the yearbook to a congressional committee if they held hearings on the allegations. Young claims Moore made inappropriate sexual advances toward her when she was 16 years old.

The yearbook reportedly has a note that reads, "To a sweeter more beautiful girl I could not say Merry Christmas. Christmas 1977. Love, Roy Moore, D.A."

Moore attorney Phillip Jauregui, who has called for the yearbook to be released to an independent examiner, suggested "D.A." were the initials of Moore's assistant at the time.

"We demand you immediately release the yearbook to a neutral custodian so our expert can look at the actual document. Release the yearbook so we can determine is it genuine or is it a fraud," Jauregui told reporters in Birmingham.

Moore, who had held a comfortable lead against his Democratic opponent Doug Jones, has seen that slip since the accusations were first published last week. The two are battling in a special election for the seat left vacant when Jeff Sessions became attorney general.

Additional women have stepped forward to claim Moore also approached them when they were teenagers. Moore, who would have been in his 30s at the time, has denied most of the allegations.
