Alabama Senate candidate Roy Moore's campaign team is demanding access to Beverly Young Nelson's yearbook that allegedly contains his signature, questioning whether it's real or a forgery and saying an expert must decide.

Nelson produced the yearbook allegedly signed by Moore at a Monday press conference with attorney Gloria Allred, where she claimed he attempted to force himself on her when she was 16 years old.

The signature in the yearbook, dated Dec. 22, 1977, is by "Roy Moore D.A.," but the reason for writing the "D.A." was questioned by Moore's team, arguing he was assistant district attorney when he allegedly signed the yearbook.

Moore attorney Phillip Jauregui suggested the "D.A." may have something to do with the initials of Moore's assistant in 1999, when the judge allegedly signed an order in Nelson's divorce proceedings. He questioned other details in Moore's alleged yearbook inscription.

"We demand that you immediately release the yearbook to a neutral custodian," Jauregui said, "so that we we can see the ink on the page, we can see the indentations, and we can see how old is that ink. Is it 40 years old or is it a week old?"

Jauregui offered particular skepticism for the "D.A" in the yearbook signature.

"Judge Moore says he can't ever remember ever signing his name with D.A. after it, but had seen it before," Jaurequi said.

"You know where he had seen it?" he continued. "When he was on the bench, his assistant, whose initials are D.A., Delver Adams, would stamp his signature on documents and then put D.A. That's exactly how the signature appears on the divorce decree that Judge Moore signed dismissing the divorce action with Ms. Nelson."

A copy of the court order was shown to reporters at the press conference. On the court document, Moore's signature uses his middle initial and is followed by a small "/D.A." Moore's alleged signature in the yearbook, which resembles at least some other publicly available Moore signatures, does not contain a middle initial.

Nelson's allegation came after four initial claims reported Thursday by the Washington Post, which quoted women saying Moore romantically pursued them when they were 14 to 18 years old and he was in his 30s, between 1979 and 1982.
