(ST. LOUIS) Missouri Governor Eric Greitens was seen entering a courthouse in St. Louis, Missouri Thursday morning where jury selection in the felony case against the 44-year-old Republican is expected to start today.

Jury selection is expected to last least two days, and testimony is scheduled to begin Monday.

Greitens is accused of taking an unauthorized photograph of a blindfolded and partially naked woman while she was bound to exercise rings in his basement in 2015, before he was elected.

The woman, a hairdresser with whom Greitens has admitted having an affair, told investigators she saw a flash through the blindfold and heard what sounded like a photo being taken. Greitens allegedly told her, "You're never going to mention my name, otherwise there will be pictures of (you) everywhere."

The woman, whose name has not been released, said that she became upset and that Greitens told her he deleted the picture. Prosecutors acknowledged in court Monday that they have not found such a photo. And Greitens has repeatedly declined to say if he took a picture.

In addition to the invasion-of-privacy case, Greitens faces separate criminal charges of misusing a charity donor list for political purposes, and the Legislature will convene in special session this month to consider impeachment.
