Ms. Hardaway, who rose to fame with one of her sisters as half of a pro-Trump duo, died in North Carolina, according to former President Donald J. Trump.
The Georgia Senate candidate, who supports a no-exceptions ban on abortion, paid for a girlfriend to have the procedure in 2009, according to The Daily Beast. Mr. Walker denied it, and G.O.P. allies are sticking by him.
Mr. Walker called the report a lie, after The Daily Beast, which has also broken news about Mr. Walker’s out-of-wedlock children, reported that a former girlfriend had the procedure in 2009.
