It’s never a glorious day for your state when your governor appears in a mug shot.

Missouri Gov. Eric Greitens experienced that dubious distinction Thursday after he was indicted by a St. Louis grand jury for felony invasion of privacy.

He is accused of photographing his partially nude paramour and blackmailing her with the release of the photo if she disclosed the relationship.

Greitens has acknowledged the affair but denied the blackmail accusations. However, he has never given a “yes” or “no” answer on the question of whether he photographed the woman.

On Thursday, he blamed the charges on a “reckless liberal prosecutor” who was seeking to score political points and vowed to fight the charges while staying in office.

Meanwhile, Missouri House members have indicated the chamber will conduct an investigation into the allegations that led to the indictment. That is the first step in impeachment proceedings.

Moreover, a growing and bipartisan group of lawmakers is calling for the governor to resign. They say there is no way he can be an effective leader while the criminal proceedings and legislative investigations play out.

They are right. The governor is a liability — to his party and to his state. It’s time to turn the page on this sad and shameful chapter in Missouri history.

If Greitens really cares about our state and its reputation, he will do the right thing and step down. The scandal has gone on long enough. It’s time for new leadership and a new direction.
