Republicans control both houses of the Missouri legislature, and they're the ones who initiated and are running the investigation. Greitens has nobody to blame on this but himself.
It was started by a democrap DA and her bogus prosecution (which is currently falling apart due to the unreliable witness and the failure to produce actual evidence).
Stupid GOPe jumped on the metoo wagon reflexively and prematurely, IMO. They should have waited until after a verdict instead of trying to get ahead of the narrative.
