The ex-wife of Missouri GOP Senate candidate Eric Greitens has accused him of physical abuse.

That's according to an affidavit filed Monday in the former couple's child custody case in Missouri.

Sheena Greitens also alleges in the affidavit that Greitens showed “unstable and coercive behavior” in the months leading up to his 2018 resignation as Missouri's governor following a sex scandal.

She alleges that associates at one point took steps to limit his access to firearms. In an emailed statement, Greitens' called the allegations “completely fabricated” and “baseless.”

Greitens announced a year ago that he would seek the GOP nomination in 2022. His announcement came 14 days after Roy Blunt said he would not seek a third term.

Greitens was seen by some as a potential future presidential candidate until a sex scandal first reported in January 2018.

A year into his term, he ran into legal trouble stemming from an extramarital affair, then a second criminal charge. He also faced ethics investigations by the GOP-led Missouri Legislature.
