Herschel Walker acknowledges signing check that allegedly paid for abortion

Herschel Walker, the Republican nominee in Georgia's Senate race, told NBC News that he gave a $700 check to a former partner in 2009, but he denied allegations that the money was used to pay for an abortion.

Driving the news: "That's my check," Walker told NBC's Kristen Welker during an interview in which she showed him a copy of the check. "I have no idea what that could be for," he also said.

• "It's a lie," Walker said of the allegations that he paid for an ex-girlfriend's abortion in 2009.

Between the lines: The woman who accused the Senate hopeful of urging her to have an abortion, as first reported by the Daily Beast, is reportedly the mother of one of Walker's children.

• The woman shared with NBC News photos of records that she said provide evidence of an abortion of a child they conceived in 2009, per the news outlet.
• The Daily Beast said that it corroborated details of the woman’s claims with a close friend who took care of her after the procedure.
• Walker says he opposes abortion, with no exceptions for rape, incest or the mother's life.

The big picture: Walker, who faces a number of questions about his past, also told NBC News that a sheriff's badge he displayed on stage during a debate last week with incumbent Sen. Raphael Warnock (D-Ga.) was "legit."

• "This is from my hometown. This is from Johnson County, from the sheriff from Johnson County, which is a legit badge," Walker said.

State of play: Early voting in Georgia, one of the most crucial battleground races on the Senate map, begins on Monday.

• "Voters should believe me because I've been very transparent about everything I've ever done," Walker said in the interview released on Monday.
