Herschel Walker accuser comes forward with fresh relationship claims

The second woman to allege that she was pressured into having an abortion by Herschel Walker, the Republican nominee in Georgia’s hotly contested US Senate race, on Tuesday presented previously unseen letters, audio recordings and pages of her personal diary that she said were evidence of their relationship, which he has denied.

At a press conference in Los Angeles organized by her lawyer, Gloria Allred, the anonymous woman known only as Jane Doe came forward anew with a raft of fresh materials. She said she was doing so because when she first aired her allegations last month “and told the truth, he denied that he knew that I existed”.

The alleged new evidence of the relationship between the woman and the former college football star included a voicemail recording in which Walker was purported to say to her: “This is your stud farm calling, you big sex puppy you”.

Jane Doe also read out a letter which she said had been written by Walker to her parents. “I do love your daughter and I’m not out to hurt her. She has been a strong backbone for me through all of this,” the letter said.

The new allegations surfaced just as early voting is set to begin in the important run-off election for a Georgia seat in the US Senate between Walker, who has publicly called for abortion to be banned, and the Democratic incumbent, Raphael Warnock, following a neck-and-neck result in the midterm elections.
