Governor Eric Greitens has repeatedly denied any wrongdoing and pledged to remain in office after a series of unfolding political and legal scandals.
The saga started in January, when KMOV released a recording of a woman saying Greitens took a compromising photo during a sexual encounter and threatened to blackmail her.
A St. Louis grand jury indicted Greitens in February on felony invasion of privacy, and the criminal trial is scheduled to begin in May. The woman testified to lawmakers that Greitens sexually and physically abused her, spurring bipartisan calls for his resignation or impeachment.
Greitens is also accused of illegally obtaining a donor list from the veterans non-profit he founded with his political campaign.
