It is the outcome of his own reckless actions in the alleged violent sexual abuse of his former hairdresser.
On Thursday, state Senate Majority Floor Leader Mike Kehoe said Greitens should step down right away "for the good of the state, but more importantly, for the good of his family".
A report released by a legislative committee investigating Greitens detailed testimony from a woman who said Greitens slapped, grabbed, shoved and threatened her during unwanted sexual encounters. Kehoe said the report's allegations show Greitens has lost the "moral authority and the ability to lead".
"When our colleagues in the House voted on March 1st for the Special Investigative Committee on Oversight to investigate certain actions of Governor Greitens, their unanimous vote was a clear sign House members required nothing less than the highest level of integrity from the committee". And they know, they need to know, that fake charges and falsehoods aren't going to stop us.
Meanwhile, Republican Attorney General Josh Hawley has opened an investigation into the Greitens campaign's use of a nonprofit donor list, an issue also being probed by the House committee and the St. Louis circuit attorney. The trial is set to begin next month.
In court Thursday, his attorneys asked for the case to be dismissed.
Prosecutors initially told the Greitens' defense team that the tape had an audio problem and was being repaired, but last night suddenly found the videotape and gave a copy to the defense team. This is inconsistent with her statements in the video interview with the Circuit Attorney.
Greitens' defense team announced that the St. Louis Circuit Attorney's office had turned over a videotaped interview of the woman with whom Greitens was having the affair an hour after the House report was released.
According to the House report, the woman recounted their first liaison as a menacing and coerced sexual encounter in which he bound her hands, blindfolded her and ripped off her clothes without her consent before snapping a photo of her and threatening to disseminate the image if their affair became public.
Kim Gardner hid a video that she knew directly contradicted allegations in the House report, and she allowed her lead investigator to lie about it, under oath.
An attorney for the woman declined comment, citing a gag order in the criminal case.
Greitens has said he'll continue to serve and that allegations of violence or sexual assault are false. He later added: "This is exactly like what's happening with the witch hunts in Washington, D.C". "He ran as something different than everybody else, and Trump was more in some ways upfront about who he was".
In their letter, the GOP state senators told Mr. Trump that the governor was taught in the military "always to obey his Commander-in-Chief".
Peverill Squire, a political science professor at the University of Missouri, said Greitens is in a hard position now that members of his own party have called on him to step down as governor.
Morris noted that the "witch hunt" metaphor dates to the 17th century, when numerous likely innocent people were accused by other residents of British colonies in the Americas of practicing witchcraft.
Sanders said she didn't have an official response but says the allegations are something the White House is taking very seriously. But he said Greitens' case doesn't cleanly fit that mold, because he's facing bipartisan criticism from lawmakers, including from some who had been among his early supporters. He said he was the victim of a "political witch-hunt" stemming from a "private mistake" that had nothing to do with his job as governor.
The legislature needs the support of three-quarters of its members to call themselves in for a special session after the governor's scheduled court trial - a move Republican leadership in both chambers back.
