JEFFERSON CITY, Mo. (AP) — The St. Louis circuit attorney has launched a formal investigation to determine if Gov. Eric Greitens committed any crimes associated with an extramarital affair in 2015.

Circuit Attorney Kim Gardner initially said Thursday that no criminal complaint had been filed against Greitens, and no evidence of a crime has been presented to her office. But she said later Thursday that after further consideration, she believes an investigation is necessary. The Republican governor acknowledged late Wednesday that he had been “unfaithful” in his marriage after KMOV-TV reported he had a sexual relationship with his hairdresser in 2015.

Greitens’ attorney, Jim Bennett, denied allegations made by the woman’s ex-husband that the governor threatened to reveal a naked photograph of her if she exposed their relationship.

An attorney for the ex-husband says he has been interviewed multiple times by the FBI. An FBI spokeswoman declined comment.

The attorney for Missouri Gov. Eric Greitens is denying an allegation that Greitens slapped a woman with whom he had an affair.

The Republican governor acknowledged the months-long extramarital affair late Wednesday after KMOV-TV reported he had a sexual relationship with his hairdresser in 2015. Greitens denied claims that he took nude photos of her and threatened to release them publicly if she disclosed the relationship.
Al Watkins, the attorney for the woman’s ex-husband, says his client told him that Greitens slapped his ex-wife during the affair. According to Watkins, the ex-husband says Greitens became upset when the woman said she had sex with the ex-husband during a period when they were trying to reconcile.
Greitens’ attorney, Jim Bennett, wrote in an email Thursday that any allegation of violence is “completely false.” He says Greitens and the woman had a consensual relationship.

A hairdresser who, according to her ex-husband, was having an affair with Missouri Gov. Eric Greitens sent the Republican an email asking him to stop booking appointments at the salon where she worked.
The St. Louis Post-Dispatch reports that the email was sent Oct. 20, 2015, three weeks after Greitens filed papers formally starting his 2016 gubernatorial campaign. It was sent to the same account that Greitens listed on a website he used in the campaign.
The newspaper doesn’t say how it obtained the email.
She asked Greitens, whom she called by his first name, to “please consider all who are involved and the circumstances around us.” She said returning to the salon “isn’t fair to me, nor anyone close to us” and that she needed to “move forward.”

Missouri Gov. Eric Greitens acknowledges he was “unfaithful” in his marriage but denies allegations that he blackmailed the woman he had an extramarital affair with to stay quiet.
The Republican governor and his wife released a statement Wednesday night. It came after St. Louis television station KMOV reported that Greitens had a sexual relationship with his former hairdresser in 2015. The station reported that the woman’s ex-husband alleged Greitens photographed her nude and threatened to publicize the images if she spoke about the affair.
The woman allegedly involved did not comment on the record to the station, which released its report late Wednesday after Greitens gave his State of the State speech. But her ex-husband provided a recording of her detailing a sexual encounter with Greitens and saying Greitens told her the photos would be released if she exposed the affair. She did not know she was being recorded.
Greitens’ statement with his wife, Sheena, didn’t address the affair specifically or the allegations, but in a separate statement Greitens’ attorney, Jim Bennett, said, “There was no blackmail and that claim is false.”
