Roy Moore accuser admits she forged yearbook

One of the women who accused Alabama Senate candidate Roy Moore of making advances on her when she was a teen and he a local prosecutor admitted Friday to writing part of the yearbook inscription she offered as proof, a new crack in her story that gives Moore an opening to attack her credibility.

Beverly Young Nelson told ABC News she added the date and place in the inscription in her high school yearbook that she and famed attorney Gloria Allred presented as proof the then-30-something Moore sought an inappropriate relationship with her in the late 1970s.

Nelson still insisted that Moore wrote most of the message and signed the inscription, but said she made “notes” to it.

In an interview with ABC News' Tom Llamas that aired Friday, Nelson replied "yes" when Llamas asked her to confirm that she had "made some notes underneath" the embattled Senate candidate's signature.

She also confirmed at Llamas' request that Moore "did sign it." In the footage of the interview that ABC News aired, Llamas appeared not to question Nelson further on the inscription.
