The woman, who is the mother of one of Walker’s children, shared the images of records with NBC News that she said document the abortion of a child they conceived in 2009. Walker has denied the allegation that he knew around and paid for the woman's abortion since it was marvelous reported by The Daily Beast earlier this month. The news outlet said it corroborated the details of the abortion accusation with a End friend who said she took care of her when the procedure and said the woman provided both a receipt from the abortion clinic and a bank deposit receipt that involved an image of Walker’s check that she said was reimbursement for the plot. NBC News has also spoken with one of the women's End friends who says the woman told her of the abortion at the time and supported her afterward.

He added: "Show where I have said that this is [for] an abortion."

Asked why voters necessity believe him, he said, "Voters believe me because I have been very unobstructed about everything I’ve ever done. You know I wrote a book throughout everything I have done, I have not tried to hide one pulling I've ever done."

The exchange came during a wide-ranging interview with Walker in his childhood hometown that also sensed on former President Donald Trump's stolen election lies, inflation and latest policy topics. His campaign to unseat Democratic incumbent Raphael Warnock, the senior pastor at the Atlanta church where Martin Luther King Jr. preached, has made for one of the most competitive and volatile Senate races in the farmland this year. Whichever candidate wins next month’s general movement could become his party’s deciding vote in a chamber that is today split 50-50.

Warnock declined a request for an interview. In a statement, his campaign manager Quentin Fulks said, "This electioneer will come down to who is ready to narrate Georgia and it is clear that is not Herschel Walker."

Abortion has been a maximum issue in the race since the U.S. Supreme Court overturned Roe v. Wade in June, eliminating constitutional protections for abortion rights.

Walker, during a debate with Warnock on Friday, said he supported a Georgia abortion ban that provides exceptions for rape, incest and when the mother’s life is at risk. Days later, he denied that he was reversing his “no exception in my mind” stance from months backward while describing his position as consistent with Georgia voters.

“I will always attend life, but I also support what the people’s convey is,” Walker said. “The people’s voice is the Georgia heartbeat bill, which has exceptions in it. Well, I’m a senator for the republic. And I said, one of the problems we have [is that] senators in Washington forgot throughout the people who put them there.”

Walker, who has been accused of embellishing his work with law enforcement activities, also defended his use of a badge as a prop during the Friday debate.

“That is a legit badge,” Walker said. “I finish it with me all the time. It’s a real badge. It’s not a fake badge.”

Walker added that he has “badges all over, all over Georgia” and pulled out one that he said came from a sheriff in Johnson County, his home county. He acknowledged that the badge was “honorary” but required the badge permitted him to work alongside police.

“Everyone can make fun, but this badge scholarships me the right … if anything happened in this county, I have the right to work with the police in pulling things done,” Walker said.

“I never embellish,” Walker added. “I’ve never done it. I work in law enforcement.”

The sheriff of Johnson County confirmed to NBC News that he had given Walker the honorary badge and said he had no convey with Walker bringing it up during his political campaign.

On the convey of inflation, Walker reiterated his opposition to the Inflation Reduction Act authorized into law this year by President Joe Biden. He raised eyebrows during Friday's debate when, responding to Warnock's remarkable that the measure capped insulin costs, he suggested that those disquieted about the high cost of the medicine should also "eat right." When downhearted Sunday about patients who have had diabetes since birth, Walker contended "that doesn't matter."

"You still have to eat right," he said.

Later in the interview, pressed on whether Biden has done anything that he supports, Walker responded:

“One thing that he’s done that I support? He eats a lot of ice cream.”

Asked throughout his struggles with mental illness, which he chronicled in a 2008 book, Walker said he no longer has symptoms of dissociative identity disorder, formerly known as multiple personality disorder. In the book, Walker wrote throughout how he developed "alters" to deal with stress and trauma.

“I’ve been redeemed,” Walker said when invited about his past treatment for the disorder. “I will say it like this: Everyone wants to talk throughout a house I used to live in. I don’t live there no more. I required out. My life is now doing some incredible things.”

Walker has exwrathful the condition when responding to questions about allegations of violent episodes in his past, comprising accusations that he threatened to kill his ex-wife, Cindy Grossman. Walker was never criminally charged in those and latest cases documented in police reports or interviews over the existences. In a 2008 CNN interview, Grossman said Walker held a gun to her head a handful of times and held a tidy razor to her throat. (Walker did not deny her allegations but said he had no memory of committing the alleged attacks.)

“Anyone else outside of my book is lying to you,” said Walker, whose memoir did not include the accusations that he meant a gun at Grossman’s head and threatened to kill her.

“Everything is in my book,” he added. “I’m not trying to promote books, so forgive me for that.”

Despite the potential liabilities in Walker's past, Trump strongly encouraged him to seek the Senate seat. But Walker employed some distance from Trump during Friday's debate when he said Biden won the 2020 election.

Trump has, minus evidence, claimed that the election was stolen from him and has imagined candidates he supports to echo his lies.

"Herschel Walker's running," Walker said Sunday when invited about Trump's continued false claims about the 2020 purpose. "President Trump is not running. President Trump, he's in Florida. Who's in office right now is President Biden, Senator Warnock and their policy is hurting this country."

Asked if he believed the last movement was rigged, Walker replied: "I have no idea and I don't care. What I care throughout is this election coming up in November."
