According to The Daily Beast, the woman -- who did not want to be ID'ed publicly "out of privacy concerns" -- became pregnant with Walker's child in 2009. She claims a short time later, Walker asked her to get an abortion. She told the outlet she went through with it, and Walker funded the entire thing.

The Daily Beast says the woman provided it with an abortion clinic receipt for $575, a "get well" card that Walker allegedly penned to her -- as well as "a bank deposit receipt that included an image of a signed $700 personal check from Walker."

Herschel, though, said the claims are complete BS -- writing in a statement shortly after the outlet published the article, "I deny this in the strongest possible terms."

"It's disgusting, gutter politics," said Walker, a Republican who's gunning to unseat Sen. Raphael Warnock in next month's midterm elections in Georgia.

"I'm not taking this anymore," he added. "I planning to sue the Daily Beast for this defamatory lie."

Walker's son, Christian, a conservative, posted a video shortly after his dad's denial accusing the 60-year-old of, among other things, threatening to kill him and his family in the past.

"I know my mom and I would really appreciate if my father Herschel Walker stopped lying and making a mockery of us," Christian Walker said on his Twitter page. "You're not a 'family man' when you left us to bang a bunch of women, threatened to kill us, and had us move over 6 times in 6 months running from your violence."

He added, "I don't care about someone who has a bad past and takes accountability. But how DARE YOU LIE and act as though you’re some 'moral, Christian, upright man.' You've lived a life of DESTROYING other peoples lives. How dare you."

Herschel said in a tweet of his own following Christian's, "I LOVE my son no matter what."
